No surprises here. Just like the lockdown on iPhone screen and part replacements, Macbooks suffer from the same Apple’s anti-repair and anti-consumer bullshit. Battery glued, ssd soldered in and can’t even swap parts with other official parts. 6000$ laptop and you don’t even own it.
In the very long term you are right. The thing is we aren’t there yet. Lots of companies are making things unrepairable for no reason right now. This is at a time when we need to produce less stuff to help the environment.
I agree we’re long way from it; but, I don’t think the secure signing of components would necessarily equates to “no reason”, though, that’s definitely not a blanket statement. Personally I’m huge proponent for locking down components with secure signing on the portable devices — less likely to experience theft, if thieves cannot get into the device nor salvage for parts (though right now they just skim passcode and reset iCloud account to circumvent it; but this can be fixed with more security around the workflow). However, for fixed devices, it makes less sense.
Yeah nah. Signing components isn’t gonna stop people stealing phones just like iCloud dosen’t now. Nobody apart from you actually wants this feature.
