Mayor Buttigieg Singles Out Big tech
Mayor Pete Buttigieg (D-South bend), who has been a Silicon Valley favorite in the 2020 presidential race, is calling out several tech giants for harming workers. In his new policy plan, Mayor Buttigieg singles out Facebook, Google and Uber for troubling labor practices, and pledges to hold employers accountable under labor laws, strengthen unions and expand protections for gig workers. “The status quo with companies like Facebook and Uber setting the rules and government sitting on the sidelines must change,” the plan says.

In those documents, CA State Attorney General Xavier Becerra says Facebook has failed to comply with its subpoenas for more information in the state’s ongoing privacy investigation.

Facebook reveals new privacy mishap involving apps for groups
Facebook acknowledged another privacy mishap: some app developers may have wrongly accessed names and profile photos of users in certain groups. Roughly 100 “partners” may have accessed this information — including 11 that had done so within the past 60 days.
