@josh after 15 years of TPMs and they becoming quite ubiquitious, I am still not seeing how they ever have been misused like this outside of theories and labs.
To me this appears to be mostly FUD from FSF/GNU.
I think if Linux OSes would actually start using TPMs properly, the net outcome for everyone would be *good*, and not bad. It would be much harder to gain persistence for an attacker, for example. And that's a massive benefit, for everyone.
