Instagram has introduced Checkout on Instagram -- an in-app purchasing tool -- as a closed beta for consumers in the U.S. Among the 20 participating brands are Adidas, Nike, Burberry, Dior, Huda Beauty, Prada and Michael Kors. "Users in the U.S. can buy from a majority of these brands starting today, with all of them coming on board over the coming weeks," said Instagram spokesperson Paige Cohen.

Jigsaw has released Tune, an experimental Chrome extension that lets users hide comments its algorithms identify as toxic. It is available for Mac, Windows, Linux and the Chrome OS. Tune builds on the same machine learning models that power Jigsaw's Perspective API to rate the toxicity of comments. Tune users can adjust the volume of comments from zero to anything goes.

Facebook has undermined privacy on its network by exposing mobile phone numbers provided to secure user accounts through two-factor authentication. That's because anyone can use the numbers to look up a user's account. One doesn't even have to be a Facebook member to do so. Moreover, there's no way to opt out of the setting, although it can be limited to "friends" only.

Google has unveiled its game plan for fighting disinformation on its search, news, YouTube and advertising platforms in a 30-page document presented at a security conference in Europe. "Providing useful and trusted information at the scale that the Internet has reached is enormously complex and an important responsibility," noted Google Vice President for Trust and Safety Kristie Canegallo.

Apple plans to launch a subscription news service at an event next month. Described as "Netflix for news," it would let customers access an unlimited amount of content from publishers for a single monthly fee. It will be based on a reworked version of Texture, the media subscription service Apple purchased last year. The monthly fee for the service is expected to be about $10.

LinkedIn has launched an invitation-only private beta of LinkedIn Live, a streaming video feature. The service initially will be available in the United States. After the invitation-only period, LinkedIn will post a contact form on its website for others who want to participate in the beta. The company will broadcast live content from conferences, product announcements, Q&As, and other events.

Musing about Facebook's first 15 years, CEO Mark Zuckerberg positioned it as a David confronting a Goliath composed of hierarchical institutions. Facebook gives the masses a voice, he wrote. It brings communities together and provides businesses with low-cost outreach. Progress has been made in addressing the new social and ethical issues raised, including protection of privacy, he said.

Apple has blocked a Facebook app that paid users for total access to all network data. The controversy over use of the Facebook Research app erupted earlier this week, with a report that revealed Facebook was paying users $20 a month for root network access to their phones. Facebook was on-boarding users of the program, which included teenagers, through Apple's Enterprise system.

The social media model has come under increased scrutiny following revelations of data misuse and news of executives reneging on some security commitments. People expecting to change the situation will need to address how social media works. This means changing not just the business model, which describes how a social media business makes money, but the fundamental technology model too.

Facebook has begun rolling out a new feature that's bound to charm political activists. Community Actions lets Facebook members create a page where they can describe what they'd like done, and set up a button that like-minded members can click to show their support. The page will show the government agencies and officials notified about the action, as well as the number of its supporters.

Disruptive innovations are only disruptive for as long as it takes competition to develop and thus create a market. Worse, for the disruptor, the niche it created can spawn other niches. Social networking provides a vivid example. First, there were networking sites that could help you find a job or a sales lead. Then there were social sites whose purpose was simply, well, networking.

Women are abused on Twitter every 30 seconds, and minority women are harassed more often, according to Amnesty International. Volunteers for Troll Patrol, a crowdsourcing project set up by Amnesty International to process large-scale data about online abuse, sorted through 288,000 tweets sent to 778 woman politicians and journalists in the UK and the United States last year.

Firework this week released a collection of shows consisting of 12 episodes that will run just 15-seconds each. The first, "Fireside Chat featuring Molly Tarlov," debuted Tuesday. Three more followed on Wednesday, and another is scheduled for release on Dec. 28. Users can download the episodes via the Firework app, which is now available on the Google Play Store and Apple App Store.

The personal data of some 100 million people who have used Quora, a popular question and answer website, has been compromised, the company disclosed. "We recently discovered that some user data was compromised as a result of unauthorized access to one of our systems by a malicious third party," wrote Quora CEO Adam D'Angelo in an online post. "We are working rapidly to investigate the situation."

Facebook at one time considered charging companies for access to its user data, according to a report based on three pages of unredacted material from an 18-page document showing portions of some internal Facebook emails, mainly from about 2012 to 2014. The documents are linked to a lawsuit, Six4Three LLC v. Facebook Inc., alleging that Facebook's data policies were anticompetitive.

Earlier this year, in response to reports that Russian actors had used Facebook to disrupt the 2016 election, I wrote a few pieces about how one might go about fixing the problem. I am not sure I have solutions for everything, but what motivates me is the sagging feeling that settles in whenever society throws up its hands and punts. We can do better.

Do you take your online privacy seriously? Most people don't. They have an ideal scenario of just how private their online activities should be, but they rarely do anything to actually achieve it. The problem is that bad actors know and rely on this fact, and that's why there's been a steady rise in identity theft cases from 2013 to 2017, often resulting in loss of reputation or financial woes.

Theresa Payton, CEO of Fortalice Solutions, is one of the most influential experts on cybersecurity and IT strategy in the United States. She is an authority on Internet security, data breaches and fraud mitigation. She served as the first female chief information officer at the White House, overseeing IT operations for President George W. Bush and his staff.

The ACLU has filed charges of unlawful gender-based discrimination with the U.S. Equal Employment Opportunity Commission against Facebook and 10 employers accused of targeting job ads at males only. The ACLU, Outten & Golden, a Washington, D.C. law firm, and the Communications Workers of America brought the class action. The complaint alleges that Facebook delivers job ads selectively.

The EU has been stretching its wings. In the shadow of Brexit, it apparently has decided it has the real enemy of the people in its sights: social media companies and Google. France is even more aggressive, suggesting that the EU's "right to be forgotten" law should apply worldwide. Given that it actually does fall within the legitimate purview of government, it is hard not to agree.

Defending against foreign interference in American elections is one of the priorities Facebook CEO Mark Zuckerberg said he has been focusing on this year. The issue is highly sensitive, and it is one that has garnered a great deal of discussion in media reports and on the Web. Special counsel Robert Mueller warned in a court filing this spring that foreign interference efforts were still going on.

Google took on French lawyers at the European Union Court of Justice this week, in an effort to fend off expansion of the EU's "right to be forgotten" judgment. The EU's attempts to broaden the scope of that judgment would be "completely unenvisagable," and it could result in impositions on the values of different countries around the world, Google argued.

The level of effort devoted to manipulating our opinions is unprecedented. Granted, a lot of this has to do with the fact that most of the "free" online services we use aren't free at all. They are trading our ability to make measured opinions for advertisers' money, and some of these "advertisers" are foreign governments. There is one question we should be asking of any inflammatory story: Why?

American consumers' attitudes toward Facebook appear to be cooling, based on the results of a Pew Research Center survey. Forty-two percent of the roughly 4,600 people who responded to the May poll said they had taken a break of several weeks from checking the platform. "Facebook's probably losing subscribers for a number of reasons," said Frost & Sullivan's Michael Jude.

An empty chair reserved for Google became the focal point for harsh criticism Wednesday at the U.S. Senate Intelligence Committee's hearing on Russian meddling in the 2016 elections. Facebook Chief Operating Officer Sheryl Sandberg and Twitter CEO Jack Dorsey testified at the forum. Several senators lambasted the absent company for being unwilling to answer important questions.

Facebook has removed more than 650 Facebook and Instagram pages, groups and accounts originating in Iran and Russia for "coordinated inauthentic behavior." The goal is to improve the trustworthiness of Facebook connections. Although it has been making progress in its efforts, the people responsible for the inauthentic activity are determined and well funded, Facebook said.

Facebook earlier this week pulled the plug on the official page for Alex Jones, host of Infowars and noted conspiracy theorist. YouTube quickly followed, removing Infowars and Jones' videos. Facebook's move followed Apple's decision to pull five of Infowars' six podcasts -- including the "Alex Jones Show" and "War Room" -- from the iTunes and Podcasts apps.

Photo-hosting service Photobucket in May quietly restored third-party hosting of photos, reversing its unpopular year-old policy that required users to pay nearly $400 for hosting privileges. Many irate users claimed their photos were "taken hostage." Hosted photos on blogs, forums and other sites were replaced by an image of a dial indicating the hosted data quota had been surpassed.

IBM just showcased Project Debater, and it just won against a top human debater using actual facts. We need the production version of this tool yesterday. The problem with fake news is that it is getting worse over time. We have always had issues with politicians and con artists trying to convince us down is up and to get us to do things that, were we informed, we'd never do.

Facebook has announced new tactics to reduce the spread of fake news. Its efforts will include combining technology with human reviewers to identify and remove fake accounts; partnering with fact-checkers; and promoting news literacy. Facebook will expand its fact-checking programs to new countries, scrutinize photos and videos more closely, and increase the impact of fact-checking.
