They’re built from essentially the same secure MCUs as traditional TPMs and both the hardware and the proprietary crypto libraries used on them have been exploited many times over.
But would you not agree that using a yubikey can improve security?
If you chose to label TPMs as security by obscurity, so be it, but it doesn’t make them less useful conceptually. Shitty implementations and complexities of UEFI do that.
