I guess I can't go forward without reiterating the argument, so I guess I'll stop. But, I think considering it easy is naive, considering the mountain of experience to the contrary.
At least in Italy, this has been the way it works for years. When I sign something privacy-related I get at least two boxes: one for the treatment of my information for functional purpose (that is, "we can't even take this paper back if you don't give us permission"), the other for research and marketing purposes (that is stuff not essential to the performance of the service). It's working quite well, in my case at least.
