Yes, remote attestation is tantamount to the hardware snitching on the execution, and not necessarily to the benefit of the platform owner. I agree with you, that from a game theoretic perspective, as soon as the vast majority of platforms betray user trust, those seeking to use other machines will be left stranded. However, despite the above dynamics, you could still buy any machine you like and use it any way you like, just like app stores have alternatives. You may not like the alternative, but that is a different story.

Knowing nothing about you, it is safe to assume that you may use the dollar or similar currency, either directly or indirectly. Why would you choose to do that? Such currencies come with lots of rules and regulations about what you can and cannot do. Society must keep track of who has how much in banks, and individuals are held liable should there be an overdraft. Remote attestation may certainly put a damper on doing your own thing with your computer, but you can choose whether you wish to pay the price of participating in the economy. Not sure if the above is a great analogy, probably a terrible one, but the bygone ideal of having your computer acting solely in your interest is simply not very realistic. At the very least, controlling the microcode will not give you the control you seek, because there are too many other layers in the stack that are routinely broken, and you are always one exploit away from joining a botnet. No matter how you wish to spin it, your computer is not yours, and obeys many masters. If you feel otherwise, please offer a counterexample to the preceding statement.
