I don’t see why Google cant just keep it apolitical in the work environment while being open to critiques externally and not caring what their employees do politically in their spare time.
Weird as it is, I don't think there's a half-open position with the free-thought floodgate.
If I was google, I'd allow it. For a while. Then get rid of everybody in there. Good riddance.
TBH, the real problem here is people's different views on the Overton window. I suspect that is why you are getting such vigorous blowback on these topics; your window isn't aligned with at least some of the people on this thread.
