Honestly? I'm not doing a damn thing. Forgive me for this, but the internet has been a walled garden for some time now, and the vast majority of humans just don't care. I haven't seen anything that's going to change that. The Internet requires a login, and your privacy being dead is a foregone conclusion.
It's easy to trash Facebook, but clearly it provides an insane amount of utility, and people aren't willing to stop using it because of others saying that en masse that is bad for a hypothetical Internet they never really took part in anyway.
IMO the focus should be getting the government to keep its hands off of it. That's not only more possible, but infinitely more important than not letting Facebook try to show us the right ads.
You will likely have to get Governments around the world more selectively involved in it.
As systems, governments are playing catch up in many areas, while leading in areas we don't want them to have power.
For example - governments should have already put out rules against skinner box games, the most popular kind on Facebook and the rest of the net.
Governments made rules against things like subliminal messaging - because it targeted and manipulated human choice at a subconcious level.
We wont be able to protect ourselves against corporations, unless we have coordinated action. The mechanism for this is always going to end up being political.
