Wait I'm confused. I remember reading a bunch of reports about how China started blocking TLS 1.3 because of encrypted SNI (eSNI) years ago?
Some people interested in the Great Firewall wrote up weirdness they saw with one particular prototype of eSNI years back. A game of Telephone later this became nonsense like "China blocks TLS 1.3" but actually if you do that what you get isn't web sites stripped of protection but connection errors. Which is indeed what happens for some sites from the other side of the Great Firewall, but we just say China blocks tho…
Funny enough the children's "telephone game" is, in many Commonwealth countries, apparently called "Chinese whispers," at least according to my Londoner colleagues.
