The problem I have is that they will take my information from my machine and my actions and sell it. They are willing to commodify my existence without giving me a cut of financial gain or the opportunity to say "no don't do that" without wrapping it up in legalese in tiny print on page 103 of a EULA.
That is just treating me the customer like shit.
It sucks. I am not pork bellies nor some stock to be traded in for cash or service. I am a human, and I want the right to control how other legal fictions (corporations) make money off of me or trade in my identity.
