there isn’t an “issue” beyond the TPM being a potential point of failure, and all x86 laptops nowadays have a similar TPM and similar point of failure.

What do you think happens if your AMD cpu dies? That cpu has a pluton security module inside and if it dies, bye bye bitlocker keys.

you’re getting downvoted because you’re spreading decade-old FUD from the days before the tech community had wrapped their head around TPM. Any secure system is going to be equally dead if your TPM dies and this very much includes every windows laptop etc.
