In 10 years of developing Go, I know of only 2 things that the community has disagreed on with the Go team - package management and generics. One is already fixed and the other will be in a year. Nothing I can think of wrt their contributions to Rust, Kotlin, C++, Python etc.
No one has ever articulated why it's a bad thing that Google sponsors open source development. If someone could articulate specific reasons, that'd be great. But this kind of FUD comment ("hmm, they sponsor an awful lot don't they") doesn't add much.
