Let's say I want to research something in private. I can absolutely connect to tor and have my identity hidden from the surveillance networks that track us all. Of course, I can't hide from the NSA. If the NSA wants me, they're gonna get me.
Also, if Google's devices or networks get hacked and used for extortion, they've got deep pockets. It'd be a cool plot for a movie, but I'm personally unconcerned about that scenario.
