As an outsider, it often feels like Silicon Valley like organisations have a particularly unique culture compared to the rest of the Western corporate world. It's built from decades of hacker culture, start-up mythos, antidisestablishmentarianism, etc. I think people are angry because they thought that Google (and others) were behaving with the same social contract, acting in their interests.

It's a tough pill to realise its just another company behaving as they all do.
