But that assumes that the bad consequences of these things will only fall on those who participated in bringing them about. I think of the data/surveillance system as being similar to global warming. Sure, it's good if I try to be more efficient and support places who do, but if 90% of the world still burns coal like there's no problem, I still get screwed in the next 50 years. I don't get to plead with the climate for mercy because I tried, and I don't get to plead with whatever Black Mirror dystopia may come because I didn't help create it. If anything, it's closer to that thought experiment around AI where if you tried to stop the killer AI from taking over the world, when it does arrive, you're the first to die because it knows you hate it. If we end up all living in Google's country or whatever, your friends with Android phones and Gmail accounts are going to be the ones faster than you and not the other way around. None of this to say you shouldn't try to effect change, but don't mistake principle with self-preservation.
