You're worried about the blacklisting of a guy who spouts conspiracy theories about "the Jews"?
The internet essentially functions as the public space these days, except that we are forced to operate on the "premises" of big multinational tech companies. But just like it should be possible for somebody to spout Alex Jones' nonsense on the streets, it should be possible to do this on the internet as well.
And he still can. He just can't use PayPal to sell his snake oil products anymore.
(And there are TONS of other payment processors. PayPal isn't even close to a monopoly.)
