I personally totally disagree with the ruling. Twitter users that want to badmouth Trump have the freedom of speech to do so - to their friends or family or to their own Twitter followers. I don't see why they should get to use Trump Twitter feed to address all of his followers, just to trash him.
By the same reasoning, Facebook should not have the right to ban anyone, and CNN's website should be forced to allow conservatives to post whatever they want on CNN's website.
