I see no incitement to violence. I really think if you are ok with taking away someone's free speech you should at least be able to provide it.
I mean I think Trump is a nasty person who would probably take over everything if he could, but to do what tech companies did I think they should provide proof. In fact from looking it up all I could find was twitter CEO saying he was afraid of what "he might do". Thought crime is a disturbing alley to go down.
