I brought up copyright as just one example, these platforms have many reasons (not always given) for deleting stuff, ranging from political content or activism to copyright. Most ToS's are quite arbitrary. People have been talking about this for a long time as well -- "Chilling Effects" turns 20 this year! At the risk of being a bit unkind it seems like it's mostly just conservatives who were "living under a rock" until now, and now suddenly have loads of opinions on it.
