They don’t sell data, they let anyone who buys ads choose who the ads go to based on anonymized data.

They also made it way harder to run political ads after public sentiment changed in 2016.

You can go buy an ad from them right now. So can “foreign groups.” Neither of you will get access to anyone’s data.

Same goes for YouTube, Twitter, Snap, etc.

If you’re worried about “foreign groups” there’s this Chinese app called TikTok that knows everything about every American under 30 that no one seems to be concerned about.
