Isn't the basic question, should youtube be forced to do something it doesn't want to? In this case, host videos it finds objectionable for whatever reason. Same way they don't allow porn for example. From the way I see it there are only a few options:

1) Youtube hosts everything that's legal, no filters at all

2) Youtube decides what it does and doesn't host

3) Somethings are ok (e.g. news / fake news), others are not (porn). Who decides what's ok and not ok if it's not the legal system or youtube itself?
