There have been quite a few lawsuits around related subjects. Facebook got sued because their targeting of ads allowed people to do things like target jobs to only men [0], or only to certain ethnicities [1], etc. Certainly, in some cases, targeting gender makes sense, but allowing it across the board gets a little scary.
Yeah but Facebook got sued for that because those violated existing laws. There’s no regulation around using any data for targeting purposes for most regular or political online ads, and I’m saying that should be the focus when it comes to regulation but have not heard anything other than “Facebook is destroying democracy!”
