Until the their payment processors refuse to do business with them due to political pressure. I guess they could accept money orders or cryptocurrency, but services are centralized to the point that "just create your own website" isn't a simple solution any more.

Even though I don’t care either way about these people, it does bother me that ISPs could take away their access. If I had controversial views where I couldn’t find anyone to host my site, I could set up a few servers in my home. Someone somewhere would give me basic DNS. I guess they could still make money via personal appearances? Farrakhan at least has shown he knows how to get his word out without the Internet.

Or their domain registrar drops them. And their hosting company. And their ISP doesn't allow them to self host. And then they're effectively blackballed from the internet.

I might be playing the devil's advocate a little bit now, but If what these people are saying is truly that toxic that they can be excluded from facebook, twitter, podcast directories, etc. If they really do incite violence and harrasment and spread misinformation.

What's stopping them from ending up like the daily stormer, being "deplatformed" from cloudflare, or ending up like the pirate bay, being blocked by a lot of ISPs world wide?

Or maybe they just deserve it if they can garner enough attention and infamy to get themselves blocked from a hosting company.
