Doesn't that mean that places like AWS will be fighting ECH, then? Right now, evil governments can block sites based on their domain; so if irrelevant-aws-customer.com does something controversial, super-important-customer-also-on-aws.com can still receive traffic. If evil governments lose this ability and irrelevant-aws-customer.com needs to be blocked, then they just block all of AWS, forcing super-important-customer-also-on-aws.com to move to Azure or GCP. As a result, I imagine that big cloud providers to whine loudly about this, unless they have some other plan. (I also think we should ignore their whining, but the #1 browser is made by the #3 cloud provider, so I have my doubts. What hurts AWS hurts GCP, probably.)
