Freedom of speech is NOT about beer
Regarding the first part, pretty much insane on its face. If they do nuke 4chan, they'll just release such pictures elsewhere. I don't believe their surface argument at all. I think it is mostly about intimidation of publication, and this is just a good wedge issue. Once they establish that your website or newspaper or any other business can be nuked for one reason, it really does become a slippery slope of trying to justify additional reasons. The real point is to create a climate of fear that results in self-censorship, the only effective kind.
Regarding the headline, I feel it was bait and switch. Not much about the google here, but having been poked, I'll say that I'm convinced the google has gone evil and that their current motto is "All of your attentions are is belonging to the google!"
