I mean I'm sure if Google specifically wanted something they could get it, but honestly I don't get the impression from any of the Go authors they are there to serve Google. They seem genuinely interested in just building the best language they know how. The fact that the features being worked on are the ones that are requested by the community tells me thats authentic.

Don't get me wrong the Go authors have overridden the community a couple of times and there was some serious outrage. Don't think that was a Google thing though, more of an "We know better" from the authors.
