At this point the primary operating system globally is Chrome. It is an overlay operating system, but still should go in that category. The web platform has APIs for just about everything else at this point. Even USB. The main reason we don't have UDP, aside from some security challenges, is probably that it actually really opens up possibilities for decentralization via direct P2P connectivity, which could rapidly decrease the control and profits of the big internet companies. Yes there is WebRTC but that is not quite the same and specifically is scoped inside of the browser. Ordinary UDP support would invite things like libp2p to be ported. Then people bringing in entire decentralized applications using web assembly.. and finally people will eventually realize they don't need a bloated overly complex browser and start using lighter weight platforms built in web assembly extended with things like UDP and cryptocurrency support etc. That will also pave the way for script/app free information browsing as it becomes popular to break out of the Google platform. So there are billions of reasons for Google to suppress UDP. They would never admit it though.
