"How Parts Pairing Kills Independent Repair" [2023-01-17] https://www.ifixit.com/News/69320/how-parts-pairing-kills-in...
TDLR: "Put Pairing in the Peoples’ Hands" and "Unpair the Future"
Their second point is totally spot on and lost in the food fight. Parts Pairing must be disabled for any discontinued models which have also fallen out of warranty. (Like if I bought the last iPhone 5 and could no longer buy Apple Care for it.)
Further, Apple must provide repair parts. Actual cost for noobs like me and discounted for warranty repair shops (any org who wants to sign up, eg identity and tax id verified.) Excess inventory for discontinued models liquidated to some one's like iFixit.
My u/unpopularopinion:
Counterfeit and grey/black markets are a scourge. I absolutely want parts pairing for any new devices. Doubly so if my threat model included espionage or surveillance.
