I assume one could start and then cancel a subscription, though, so you could just pay about a buck every time you want to use the app. That’s a lot of friction, though.

I have iCloud+ base tier, but I use it just for iMessage, Drive, and other non-photo apps (I back up my photos to my NAS). I don’t back up my whole phone because all the data I care about is already backed up. I also like being able to use Private Relay when I want. All that is to say that for me the $1 plan is great and I still have plenty of space for shared album photos from events (which I later will move off of iCloud). But I get that I’m a pretty unusual use case.
