seriously? 10 years is an eternity in tech, and if they really did lock down the desktop a few years from now with some new system (eg. pluton), I'm not really sure that you could say "I told you so" or "TPM caused the platform to be more locked down". It'd be like predicting some sort of smallpox attack by china in 2010, then claiming you got it right in 2020 because of corona. The only plausible scenario where you could plausibly blame TPM/UEFI is if OEMs suddenly decided to remove the ability to add user keys and/or disable secureboot.
