I don't care that my data is being mined left and right for marketing purposes. CMV

When it comes to what directly affects me, it boils down to either an ad I might actually be interested in (peaking my interest towards buying something I might want, a win-win for both parties) or an ad I have absolutely no interest in (and would consider annoying, a loss for both parties.) As for behind the scenes, yes, they might know "important" things about me, but why would they ever care about *me*? I'll always be a number to them, no more. With this in mind, I really do feel like the visible benefit outweighs the invisible cost. CMV.

You're assuming that only disinterested parties will ever see this information. There are numerous ways that the data can leak, for example the company's database can be hacked or the government can demand that they hand over the data.
