> A pretty interesting feature of ECH is that the server does not need to validate the public name (it MAY) , so clients can use public_name's that middleboxes (read: censors) approve to connect to other websites. I'm trying to get this added to the RustTLS client[1], now might be a good time to pick that back up.
Note that it is exactly this type of thing that makes age verification laws reasonable. You're making it technically impossible for even sophisticated parents to censor things without a non-solution like "don't let kids use a computer until they're 18", so naturally the remaining solution is a legal one to put liability on service operators.
You're still ultimately going to get the censorship when the law catches up in whatever jurisdiction, but you'll also provide opacity for malware (e.g. ad and tracking software) to do its thing.
