Twitter and Facebook are not just any domestic firms, they do control a major part of social media. They may not have a legal responsibility to hold every post to the same standards, but if they enforce their policies selectively on political grounds, that should surely raise some eyebrows. Anyway, if Twitter/Facebook ever had the intention to stop dissemination of that NY Post article, it surely backfired.
