Google's former global head of international relations claims he was pushed out of the company for trying to protect free expression and privacy in China. In a letter shared today, Ross LaJeunesse says that, after 11 years of working to protect human rights in China, he was told there was no longer a job for him as a result of "reorganization." He says the company has strayed from its "don't be evil" motto, and rather than take a lesser role, he's leaving to run for a Senate seat in Maine.
