U.S. government officials ratcheted up pressure on Facebook Inc. on Monday over its handling of user data, with federal regulators saying they are investigating the social-media giant’s privacy policies and 37 state attorneys general demanding explanations of its practices.

Several lawsuits have also been filed by investors and Facebook’s users, plus by the Cook County government in Illinois.
Plus, the US Department of Justice and the US Federal Election Commission are investigating Cambridge Analytica/Facebook and their involvement in U.S. elections.
Update: And the United Nations may be investigating Facebook’s role in elections in Myanmar.
And this goes with my earlier comments about Facebook potentially using phone and text message records to track one’s use of physical and mental health facilities:

The second suit claims that Facebook has been capturing and selling the details of users’ browsing of third-party health sites. Any site with a Facebook “like” button, including those of medical institutions such as the American Cancer Society and the American Society of Clinical Oncology, could be used to track users as they browsed outside Facebook, according to the lawsuit.

Against that back drop there are financial analysts saying now is a great time to buy Facebook stock. Of course, “because its different this time”! More likely, their firms own a bunch of FB stock and want to unload it on idiots.
