I think Twitter holds exactly zero power over Trump which is why they won't do anything about him even though they would certainly love to. He is bringing them traffic and giving them more legitimacy than they have ever had before. If they banned him he would just switch to another social network and spend the next year telling his supporters to boycott them and then find some creative ways to shaft them through the regulatory state. Look at the situation with CNN and the ATT/Time Warner merger. Twitter is a very small fish compared to them.
