It's not in the same order of magnitude (and maybe off-topic), but from the leaked documents of Twitter, Google was directing much of the Twitter APIs implementation, from their tone. And twitter was in the boom stage (2009, sorry can't find a source, techcrunch iirc).

I don't have any experience in acquisitions by large companies, but from the twitter story (above) I made an idea of the tension going on. It's like you're a soldier and their the commandant during a war, most of the time you just can't say no.

edit: I meant, if you say no, you have to be prepared for the consequences.

I wouldn't call someone who is working on the "poke a friend" or "throw a sheep" features a "hacker". While the audience is large, facebook isn't changing their lives for the better. The user base may think so, though, just like with the TV.
