Apple has previously said they want a large user base (hence why they are giving upcoming OS26 to older devices) as they are seeking to maximise the sales of software, accessories and subscriptions.
The more apple devices in circulation, the more 30% cut from App Store, Ai Services, apple TV, music,games, earbuds and everything else.
They are now like a video games console maker selling games and accessories, except unlike console makers, they don't sell the device for an initial loss but profit.
