Facebook announced Friday that it suspended "tens of thousands" of apps following a lengthy investigation into the third-party developers that share data with the tech giant.

Why it matters: The company is facing immense regulatory pressure over its privacy practices and data dominance. In particular, the Massachusetts attorney general's office has reportedly been working to unseal documents related to the app investigation.

Be smart: According to The New York Times, Facebook last month petitioned a judge in Boston to seal the records, but it's likely they will be unsealed by a state court soon.

  • "It seems Facebook only cares about privacy when it’s their own," Massachusetts Attorney General Maura Healy tweeted in response to the news.

Details: Facebook says the investigation targeted apps that had access to large amounts of user data before the company changed its policies to limit such access in 2014.

  • The company says the probe, which involved hundreds of people, from lawyers to data scientists, is helping to better identify patterns of data abuse by developers to root out bad developers from being able to access more data on its platform.
  • Facebook also said in a few cases it banned apps completely. Those apps were banned for a variety of reasons, like inappropriately sharing data obtained from Facebook or making data publicly available without protecting people’s identity.
  • The company explains it has also taken legal action when necessary, like filing suits against companies that failed to cooperate with its investigation.

By the numbers: Facebook says that while "thousands of apps" have been suspended, most are associated with around 400 developers. It says not all apps were live, and some were just being tested, but because many app developers didn't respond to Facebook's request for comment about them, it suspended their apps.

The big picture: The investigation, which launched in March 2018, was triggered by the now infamous Cambridge Analytica scandal, where a third-party developer used data from Facebook users in a way that wasn't clear.

  • The Cambridge Analytica case shed light on a wider problem within the tech industry of companies placing too must trust in third-party developers to do the right thing with user data they've been given access to.

What's next: Facebook says it's working with policymakers on policing bad app developers and fraudulent data collection.

  • It notes that its new agreement with the Federal Trade Commission, which came as part of a historic $5 billion settlement over privacy violations earlier this year, requires new oversight of app developers.
  • Facebook says it developed new rules to more strictly control a developer’s access to user data, including suspension or revoking of a developer’s access to any API that it has not used in the past 90 days.

The Supreme Court ruled early Tuesday that federal executions can resume, reversing a lower court decision and paving the way for the first lethal injection since 2003 to take place at a federal prison in Indiana, AP reports.

The big picture: A lower court had delayed the execution, saying inmates had provided evidence the government's plan to carry out executions using lethal injections "poses an unconstitutionally significant risk of serious pain."

More Republicans say they're wearing masks

Data: Axios/Ipsos poll; Chart: Andrew Witherspoon/Axios

Nearly two-thirds of Americans — and a noticeably increasing number of Republicans — say they’re wearing a face mask whenever they leave the house, according to the latest installment of the Axios-Ipsos Coronavirus Index.

Why it matters: A weakening partisan divide over masks, and a broad-based increase in the number of people wearing them, would be a welcome development as most of the country tries to beat back a rapidly growing outbreak.

Buildings are getting tested for coronavirus, too

Testing buildings — not just people — could be an important way to stop the spread of the coronavirus.

Why it matters: People won't feel safe returning to schools, offices, bars and restaurants unless they can be assured they won't be infected by coronavirus particles lingering in the air — or being pumped through the buildings' air ducts. One day, even office furniture lined with plants could be used to clean air in cubicles.
