Blacklisted chips break used‑PC market

Anti‑cheat systems can tie bans to physical components (a CPU or motherboard), and those bans can persist when parts change hands. Buyers of second‑hand parts can inherit enforcement blocks with little recourse if vendors refuse to delist devices. — This raises consumer‑protection, resale‑market and surveillance questions about how platforms identify hardware, what data (e.g., TPM entries or behavioral fingerprints) is used, and whether regulators or industry standards should limit persistent device bans.
