^The manufacturers love these efforts because it means more bricked phones, which means more phone sales.
Apple already has the thing where the phone can't be factory wiped and sold as fully functional. I'm not sure about the stats, but the result might be summarized as "doesn't work."
The idea that manufacturers should make it impossible to part-out a phone also means that phones can't be fixed. That's just a dumb idea.
How about letting people take care of their own stuff, and if they don't, then they need to buy a new phone? What's next? Require wallet manufacturers install trackers so people who get pickpocketed can watch where their wallet goes? GOML!
Well if they make it easy to resell parts of phones like cars, you have greater incentives for phone theft since on a thousand dollar phone, they can sell parts to various repair shops.
Apple has been criticized for making it difficult for independent shops to repair iPhones, including swapping out parts.
They claim that they can't let anyone replace key components which would compromise biometric security measures such as fingerprint or face detection sensors.
Biometric authentication is in many ways considered more secure than passcode or password authentication by financial institutions, which have adopted them for their mobile apps.
So the idea is not to make it easy to break the chain of custody for the security authentication infrastructure of a phone.
But they are now cooperating with state laws which require making it easy to repair phones.
Honestly, if I had a problem, I'd only go to an authorized repair shop, not some guy at a strip mall who may not be there in 6 months.
When you go to Apple Stores, they will swap out the whole device, rarely send away for repairs.
But iPhones are a premium product and their repeat customers tend to be higher income, big spenders. Kind of like people who buy certain luxury brand cars and spend big money to have the dealer do the maintenance and repair work rather than looking to save money by going with local independent garages.
I would guess that the nicer Android phones like Samsung and Google Pixels are similar in policy.
