Living in EU, and I am thrilled at the party we will have, when 1-2 million people/facebook users will send this letter to FB [1]. I strongly believe that this will hurt them financially (where it actually matters/hurts).
I (try to) sinkhole every tracker, advertiser etc. on my PC and jailbroken iphone. I am sure that I don't block every one, but 90% is better than 0%.
It may keep me busy, but when I start receiving the answers that FB, Amazon, etc. have provided my data to XYZ broker, and then I will be more thrilled when I send THOSE guys the same letter.
Of course after every inquiry they will be receiving a "right to be forgotten" letter.
Hurt them where it does until they learn to respect people and not see them as items to be traded.

Ps: I am not a hater. I enjoyed FB until it started to try to manipulate me e.g. altering my timeline and showing me what THEY deemed is 'good for me' (profitable for them).
Pps: They make enough from advertising. It was excessive greed that got them to start the sell-out.
