The big problem...
...is that idiot users don't care. If all they have to do is click accept, and then get "free" stuff, they don't care. Google has made billions from people willingly giving away their privacy. So has Facebook!
What good is it to have data protection laws when the public at large doesn't care?
When I ask people around me why they are giving their data willingly to the slurpers, they look at me like I'm some kind of wacko...
