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.
What takes up the most space in iCloud, such that the free 5GB tier isn't enough?
I get that the iCloud tiers start cheap, but having 50GB doesn't really do anything for me since it's still not big enough to back up an iPhone. And there's zero chance I'm going to start paying for a monthly service in order to get access to an evite clone that I would use a couple times a year. Maybe there are big partiers out there that would upgrade just for this, but this seems like an impending flop to me.
