I haven't read this carefully enough to decide exactly how bad it is, but one thing seems clear to me: From what I see many techies are now aware and upset, and hardly anyone seems to want to defend Google anymore. I consider it more likely than not that Google will take some real beatings in the years to come. Kind of like Microsoft was fined by the US and EU, forced to advertise for competing browsers and ridiculed…
To me, the explanation is simpler: people don't want to defend Google on HN because they'll get downvoted or shouted down because of it.
