This person has very strong opinions on a protocol of which they profess little knowledge. They seem to think that HTTP/3 somehow 'handles' the fallback to TLS/TCP. When in reality the browser will fallback to an older HTTP protocol over TLS/TCP. Adoption by their corporate network is not in any way important to the success of HTTP/3, in reality mobiles are the primary target market.
