We've banned this account for serially posting corporate propaganda for Google, which you've been doing on HN for years. Since banning dozens of your accounts hasn't convinced you to stop, I'm going to post about this increasingly loudly until you do stop. You should think about the many Google employees on HN, who overwhelmingly use this site in good faith. They represent Google the right way, by participating honestly in threads and commenting about what they know. They will cringe when they hear what you are doing—which if you keep doing it, they will. The agenda you've been propagating is a way to hurt Google, not help it.
We ask HN users every day not to accuse others of astroturfing or shillage, but the other side of the contract is that when we find real evidence of it, we crack down.
Edit: I should add, for those who are worried about bias, that we have nothing against Google and are only interested in protecting HN against abuse. People do that for other companies too, not just Google, and we're just as against it in those cases.
