An infinite number of typewriters gets you every time
The chance of exploitation is miniscule...and you get an unlimited number of attempts. I think I see the problem here.
So... we've built basically an entire world full of computers with a hardware backdoor, but fortunately only *trusted authorities* have the key to that backdoor. Only now the key is leaking. Time to pretend to be surprised and shocked and double down because a) this was never really a backdoor it's a handy tool for administrators, and b) this doesn't invalidate the need to put backdoors in everything else as well, which also aren't backdoors but desperately needed to protect you.
"[EPID] is used for things like providing anti-piracy DRM protections, and Internet-of-Things attestation"
Translation: the point of EPID is to ensure that you, the end user, do not have control of your computer. This is why its compromise is a disaster of biblical proportions. If your computer is compromised that's sad. If /their/ telemetry and DRM content is compromised, cats and dogs sleeping together, mass hysteria.
