Experience can differ between companies and languages. I have been involved over the past year with Julia which is mainly ran and developed by the company Julia Computing. One might say that it is the equivalent operating scheme as the companies you mentioned. However, my experience with the community has been vastly different. If you go over the development issues list it is extremely satisfying to see how many are raised by the community and adopted into the language. In contrast to the omnipotent response of Google with the Go community. Having such differences implies that a company ran open source language can indeed be influenced by the community.

Having said that, just because it exists in Julia does not mean it can exist in Go. I just wanted to mention that there are exceptions to the rule which begs the question if it is a rule in the first place.
