Earlier quoted context omitted.
Wow I think this unroll.me thing is the real scandal here. I am an unroll.me user, but had no idea they sell user data to companies this way. Their whole value proposition is to help people control their own privacy and now I kind of feel betrayed..
From their own site: "Unroll.Me is a free service ", emphasis added. If it's free for you, you're the product.
So hypothetically, if you paid $5 a month for this service, you would be confident they were NOT selling your information?
Since the answer is obviously no (and in fact, purchasing behavior is the juiciest stuff to sell, be it Comcast, Target, etc), then this tired trope is meaningless.
