At all levels, and Cloudflare isn't exempted from that. Social media platforms already routinely decline to host content via moderation.
Mainstream social media also largely does not moderate nearly well enough to uphold the standard that you are applying to Cloudflare.
I don't think that's right? Legally we've set things up so that no matter how despicable your site is, your telco or ISP can't decide on their own shut you off. They're regulated as infrastructure, and are required to keep doing business with you. They'll shut you off if they receive a court order, but not on their own judgement.
