It's in part that exact attitude that allowed somewhere between 3 and 60 million (citation: Wikipedia article for "Joseph Stalin") people to die under the Soviet regime. How exactly do you expect an unarmed, suppressed peoples to take over an armed, trained, and extremely well-funded government? Sure, it happens sometimes, but rarely does it happen without external support or out-of-the-ordinary circumstances (say, like the bad government being based halfway around the world in the case of the US revolution, not to mention the French support).
From personal experience, the people in those oppressive regimes oftentimes root for the enemy. At least, I know this was the case in the Soviet Union and is the case in Iran.
So it's quite easy to say "It's not our culture, why do we have the right to fault them for silencing and killing their citizens," but in the end that's just a really lame way to avoid the reality: you're sitting by and doing nothing while people are being oppressed and killed. It doesn't necessarily make you evil, as there's nothing that necessarily obligates you to care, but it does make you less good than the people that are at least trying to do something about it. And in this case, in some tiny little way, Google is at least trying to do something.
