If you want to assault Andrew's credentials as a staunch defender of free speech, etc, you are going to have to do better than "he worked at Google".

He worked at Google at a time when Google really was on the front lines of defending this stuff, and he was the one doing it.

If you want to blame Google, blame Google. Amac is pretty much unassailable, IMHO. He was on the right side of every legal/policy decision I can think of during his tenure. He eventually left, IMHO, precisely because he saw an opportunity to be a staunch advocate for these kinds of things at twitter.
