None of that bears any relation to what happens in the Go community.
Google is not a monolithic entity. The Go team operates pretty much independently from gmail and other stuff. Yes, there is a problem with Google randomly disabling accounts, but this doesn't really extend to Go, who make their own decisions on who to ban or not, and which are all manual. Just as you can comment on, say, github.com/facebook/zstd without a Facebook account, you can also comment on github.com/golang/go without a Google account.
