The interesting thing is it seems on the surface that Google did invite these kind of discussions in their forum probably by the nature of forum, the explicit rules about sharing ideas to improve the company, the product etc.

Now one of the valuable lessons one learns operating in any large institution is that yes there are stupid questions no matter if the policy explicitly states there aren't, and there are always unwritten rules. Failure to discover the unwritten rules leads to getting fired, let go, skipped by during a promotion, etc.

Just curious, what do you think would be a proper venue. Tweeting at Google HR publicly, private emails to owners / upper management?
