I think overall the FB aspect of the story was minor in comparison to what the author was really saying. Yes he suggested how bad Google wants/needs social. That aside, he's writing to say that it's not a fun environment to work in. The shift in company came with Page, revenues became key, trust went out the window, profits before innovation, etc. Most things start off pure and then ultimately turn to what their nature is. That's profit. Simply it seems like a story where the author started working under the premise or environment of purity and that changed to a more profit driven mentality under Page. Rock bands get the same way. Start pure then success breeds profit breeds less enjoyment. Usually bands members leave or they break up entirely. Google was that rock band. I get that. I think that's all this guy is saying.
The reality is I'm sure Goog had 1000 applications for his job. That might say something. Regardless of change I'm sure it's a great work environment, although it might be different in direction. So long as the shares rise, I'm sure most people are okay with following company lines.
