Also, not every iPhone costs $1000. There's the $400 iPhone SE, there's the entry level $329 iPad 9, there's the discontinued iPod touch, and there's also the second hand iPhone someone bought off the grey market in lieu of a brand new iPhone from Apple. I assume that one of the chief reasons Apple is willing to support their devices as long as they do (even if it comes at the expense of some users holding on to their devices longer and upgrading less often) is because of the expectation that these iOS users will still earn Apple some money by way of sales of additional accessories, apps, subscriptions and services like Apple Pay. It's all connected, and it's all factored in.
At the heart of the matter, I maintain that Apple is entitled to monetise their IP however they wish by virtue of them selling a vertically integrated product. The right way to approach is if the EU had acknowledged this right from the very start, while also stating that this has to be balanced with the good of society as a whole. Instead, they decided to wage a war with Apple (the optics of which are somewhat coloured by their apparently blatant and open support of Spotify, a home-grown company), and so long as the EU refuses to be honest about just what they are trying to do, I support Apple's decision to keep pushing and testing every boundary of the DMA until we get real clarity about what is being asked.
