There is a slight difference in that all those tools are the basis for their companies' commercial offerings. Google does not sell Go tools or consultancy hours etc. Its interest in Go is to have a programming language that's safe, fast, operationally undemanding and fits the mental model of a recent CS graduate (as per that notorious Rob Pike quote).

This at least makes it easy to work out if incentives are aligned. Do I want to program in such a language? Yes? Then Google is probably not going to completely screw it up, even when they make decisions I disagree with. Do I like to wax rhapsodic about parser combinators? Not ever going to be a good fit.
