Re: But how?
Problematic is one way to put it. Not actually solving the elephant is another.
Censorship bypass requires that the censoring authority cannot know the private key. And if they intercept 8.8.8.8 (for example) then the public key given to the client doesn't have to be the real server's one. The terrific firewall™ can simply MitM the client hello and decide whether to drop your packets; you just used their key.
The headline implies that this is a SNI fix, whereas this solution kicks off to the never never the actual magic needed to solve it.
