They aren't censoring anyone. People can pay to host their own infrastructure. Crypto projects are a legal liability for service providers and frequent abusers of service offerings. I honestly wish they would have been less specific in there reasons to not make it seem like some ethical dilemma but point is there are good reasons to not allow these types of projects. I don't trust them less I just know not to host certain projects there and follow a general etiquette. If I wanted to use them to host something more controversial then I'd reach out first to see if they'd allow it and build that relationship. This is no different than wanting to display a controversial banner in a private establishment. They end up taking on some liabilities which I'm sure they would like to be informed before doing so in order to make sure they will help provide some support if it becomes a challenge.
