If I state here that it is scientifically expected to see more foos than bars on HN, and then get banned because of it, that wouldn't become HN's manifesto, either.
I fear that, a few years from now, people will say it represented Google's official standpoints (which it doesn't) or those of a significant portion of its employees (which may or may not be the case, from what I know)
"Google employee's manifesto" or "James Damore's manifesto" are better names.
