I guarantee that there will eventually be a vaguely similar (but different!) stack published by each of: NetFlix, Microsoft, Amazon, and Apple. Just kidding, Apple won't publish anything. The IT ecosystem has fragmented into mutually incompatible cliques. You are either in the Google ecosystem, the Amazon ecosystem, or some other one, but there are no more truly open and industry-wide standards. Look at WebAuthN: it…
HTTP/2 is that. The version 3 is... quite great, and not really originary from there.
And gRPC is some self-contained thing that doesn't bother anybody.
I do really agree with your point. But those examples are bad, and yet another non-standard cloud service isn't also a good example.
