I think the fact that Google is now officially removing the Don't Be Evil principle from its code of conduct is a hint to all of those principled people that are still working there that "hey, we don't want you, so why don't you get lost?"

Silently removing the Don't Be Evil principle may have been subtle, but I'm sure it was a loud and clear message to everyone at Google, especially as it happened right after many protested the company's work on autonomous killer robots (okay, okay, the "killer" part will be added later, so that Google can plausibly claim utter ignorance).

Those who protested Google's work with the Pentagon specifically mentioned the Don't Be Evil mantra. And now Google is getting rid of it. I think that clears everything up about the type of company Google is turning into.
