Google's motto used to be "don't be evil." If someone is looking for a company that aligns with their values, Google might've seemed like a good fit. They work hard and become invested in their workplace. It's not absurd to see how several people would be disenchanted with Google's stances on a very controversial and deadly war. And in an effort to live up to the motto "don't be evil," the workers took a stand to change Google's actions. That's a good thing to do.
If people think that workers should just keep their heads down and politely obey, well, I don't know what to say. That's bleak. That's a sad society. It's like the American propaganda representations of sad, dreary authoritarian communist countries. Stay quiet and work, or face the consequences.
