True. However the control really only extends to the name and the amount of human effort allowed by employees on the Google implementation, as far as I can tell.

If Google decide that they were no longer developing their implementation of the language and moving the employees to other things, there's nothing stopping a foundation from being established. It would be ideal if this was organised by Google as part of their exit, but failing that I would expect other stake-holders in the language to organise something.

What advantages would moving to a foundation like structure bring to Go?
