I think that the move of Facebook on banning ICO ads now is not a single move and I think this is a move that is planned before Facebook announce it, as i can see how Twitter might follow the step of Facebook and Instagram. If this happened then there will be a site or a new social media that will entertain the cryptocurrency which will be funded by this group. This movement is getting nowhere but setting a platform where they can earn from cryptocurrencies. Facebook has paid advertisements but ICO doesn't need to pay them as people who join the bounties do that for them.
