You're making a big deal about "bought" but it doesn't really matter whether money changed hands. godoc.org existed, Google showed up, and now it does not. The thing that replaced it is not functionally equivalent, full stop. Whether or not someone got paid is not of interest. When Google shows up to a project, money tends to follow, so it's not really surprising that OP should make this assumption.
I'll not address any of this bizarre hypothetical law interpretation, except to say that SQLite, a software package which Google ships globally, is in the public domain, always has been, and none of the things you bring up seem to matter at all anywhere except web forums, which are consistently the only place anyone sees this kind of handwaving.
