What is? It's a workplace. You don't like what the company does? You're free to quit, and/or to say whatever you want. Post online, go to the park and have a march. Stop using their products. Put a big banner in front of HQ. Or even...do a sit-in of the CEO, if you like. Just don't be surprised when you get arrested. If you work there, don't be surprised if you get fired. Your right to free speech does not extend to private property, and Google does not have to respect your opinions.

But it is the pinnacle of entitlement to think that you can storm into a private place and not suffer consequences for your actions. Even more extreme, to do so as an employee of a company and believe you will not get fired for doing so...I don't know where people get these ideas.
