Ask HN: Free speech friendly VPS hosts?

Your best friend here is to simply not be loud enough or known enough for someone to care. Even Cloudflare, whose founder doesn't believe in them interfering with content, decided not to harbor Nazi websites once they got attention for it.

Bear in mind, what you're asking here, is for a company to put their own reputation and business on the line to protect you. If your content is not welcome in the mainstream, a company hosting you faces boycotts, protests, resignations, leaks, etc. Even amongst people who would agree with you, they probably wouldn't be willing to take their own business on protecting yours.
