OK now it makes sense. If you presume everything must go over https and sometimes you have little to no activity and want to back push events on a stream started by a client, tcp seems horrible! :) Its hard trying to push in the wrong direction, not having udp when its needed. And not having stable unNATed IPs because addresses have run out. Not sure that is TCPs fault tho. Arguably that is www + ip problem. More and more HTTPS is the only Internet allowed. This is bad IMHO and leads to stupid hacks like websockets. Gamers used to open port in their routers in my day and would receive a performance penalty if rhey did not.
