Earlier quoted context omitted.
Alex Jones is a much less serious threat then 2 or 3 large companies deciding what can discourse can be promulgated. (not a Jones supporter. nor can I imagine how anyone would be)
My point is that they don't get to decide that, though. They decide whether they will pay for hosting, but they can't stop him from paying for his own hosting elsewhere. Likewise, if the WSJ decides not to publish my letter to the editor, they aren't violating my freedom of speech, they are just deciding not to amplify it.
The "host your own" argument is done to death truly. If one type of speech can be hosted for "free" by a company with 80%+ market share, so should another without discrimination.
To allow otherwise is to risk of erosion of our values and enable corruption. Even if you don't like Jones.
