> Almost every battery in a phone is a 'non-standard' shape
The metaphor is not literal.
> Making knockoff components using Apple's logo and such is not the same thing
I think I was misremembering the lawsuit you are probably thinking of.
> Where, exactly, is this message on an iPhone
Again, the metaphor comparing iphones to cars is not literal.
Whoops! I guess you got me!
After all it really is actually super easy to buy new parts for Apple products either from Apple themselves or the thriving third-party market!
And on top of that, once your local repair shop has the parts, they are super easy to install.
Surely my damaged iphone mini 12 will be easily repaired at a reasonable price by the skilled technicians at the Genius Bar who have parts in stock and tools ready to go. It would be absolutely wild if their price for that service was based on the price of the latest iphone rather than the cost of parts and labor for the actual service. But certainly they wouldn't be able to get away with that due to, as we agreed earlier, the thriving market for third party parts and repair.
