>But once cloudflare no longer wants you, your other options have a tendency to evaporate as well
This! If the forces persecuting you made Cloudflare to drop you, and you go, you establish your own site and your own platform your own infrastructure, unless you have some billions lying around to put fiber optical cables over the oceans physically connecting your servers to the rest of the world, you will depend on other people. And the forces persecuting you, they could just go the next level and start to demand Tier 1 providers to drop you. And the whole thing start to derailing into a cat a mouse game. Where you will have to constantly be thinking "Okay, what is their next move to deplatform me?"
Because as you said. Usually when Cloudflare drops you... it's not very absurd to assume banking institutions, Mastercard, Visa, Google, Microsoft, Amazon, etc... will also drop you. And the law pretty much allows those multibillion dollar companies to deny service to a paying costumer, which is a pretty dangerous precedent in my opinion.
