They're building on that argument.

If official parts get locked down, then anyone that angers the company or wants to do their own repairs needs a new source of parts.

I see, thank you. I completely missed that additional layer.

That's essentially what Apple does but it doesn't make iPhone theft any less appealing to thieves.

Apple didn’t lock the parts yet afair. I recall a couple years ago they tried to lock screens and a lot of devices bricked. But I wish they locked them: where I live virtually everyone I know have their phone stolen at least once.
