Or, perhaps, apple users are rational actors that have different weights to their tradeoffs than you.
The last time I checked Android, the security and privacy story was much worse than Apple. Further, it's not just me who has to make the change - it's the family I share photos and videos and other things.
Yes, I would prefer to have other App Store options, but it is balanced against other issues. (And yes, I have owned an Android phone before - every time I buy a new phone I compare the two again.)
Nope, they're not rational actors by supporting marketing-driven limitations. These limitations are not needed to create a well-working device, they're only there to keep the profits up because heavens forbid, someone might offer an alternative which allows users to get their software fix without paying their pound of flesh to the app store.
The example you gave on it not just being you who needs to change but the family I share photos and videos and other things [with] is all the more proof that you shouldn't touch these mobile prisons with a 3-metre pole. I share my photos and videos and other things with family as well but I don't care what they're using to access them 'cause I use a (self-hosted, but that is not essential) web service for it. No lock-in, no nothing. If you want to view those photos on your Commodore-64, have at it. There's even apps you can use, including one for those stuck on fruit phones.
I don't believe the 'security and privacy' story the fruit factory pushes, there've been far too many examples to disprove the narrative. Not that I trust Google, mind you. I use Android but I do not use Google, do not have a Google account, don't have Google services (etc.) on my devices.
