TLS and SSH has quite different attack vectors so sure, basing SSH on TLS 1.3 would prevent the problems SSH has, but also bring in the problems TLS has. Thing is, I much prefer SSHs tradeof for things SSH is used for while TLS could be argued makes a lot more sense for the HTTPS use case. It just very different chains of trust with very different weak points, just pointing at TLS 1.3 as a solution when talking about SSH is quite ignorant.
It’s not though, like they say themselves it’s only a reconsideration of the existing policies which is to maximize profit, morals be dammed. First they welcomed Nazis because Nazis gave them money and now they don’t because Nazis cause other people to stop giving them money. If Nazis wasn’t bad business nothing would have changed. This whole ordeal showed what kind of people they are.
