This is a most excellent place for technology news and articles.
You're not wrong. And unless the controllers have some sort of TPM module in them then yeah they'll be easily bypassed.
Legacy official controllers don't have a TPM so even if new ones do, current ones don't and same goes for ones that spoof current official controllers.
At least assuming they're going to keep compatibility with current official Xbox controllers.
