As a user - why should I trust your software with my computer?
There is great imbalance of power, the companies aren't necessarily the good guys. It already got unfair with DRM, for example together with DMCA is effectively blocking fair use, like ability to make own backup copy of purchased medium, or purchasing it once and being able to play the content on multiple devices.
It also prevents one from being able to sell their copy to someone else which also is allowed by law.
But this is exactly the idea of trusted computing:
"Prove to me that I can trust your hardware to run my software according to my specifications, and I will use it to compute things (for our mutual benefit) that I would otherwise only compute on my own hardware."
DRM is the canonical example, but wouldn't it be nice to be able to actually know that cloud service provider has to adhere to their terms of service, rather than having to take their word for it?
(The big "if" here is that the terms of service are expressible and enforceable in the context of some piece of software.)
