Clearly rhetorical, but the reason is that's where the audience is. They will tolerate a lot for that reason but there's presumably some limit. I would not be surprised if whenever Trump leaves office, he announces he's leaving twitter for some twitter clone he's a part owner of geared for conservative audiences. He might be big enough and important enough to his supporters for this exodus to actually be meaningful.

Don't think he'll do it until he loses an election or his 2nd term is up though.
