One app that I bought on the app store for 60€ just refused to start one day if I didn't buy an additional annual subscription.
When I complained to Apple, they just told me to contact the developer.
They take 30%, but they don't care one bit if what they sold you actually works.
Products must be of acceptable quality, that is:
- safe, lasting, with no faults.
- do all the things someone would normally expect them to do.
Now add that you can’t even be sure that apps you “purchased” will continue to be available.
The app store model is broken, there’s also zero chance that I will buy anything from any app store anymore. I’ll download free apps that solves a problem, like buying a bus ticket, but that’s about it.
Apple does give a crap about the quality of their app store, as long as there’s no porn and you both directly steal, they simply do not care.
On the Mac, as on Windows, you could just keep using an old app for years. It didn't matter if the developer bothered to update their app for the latest OS, you could generally just keep using apps that you bought years ago.
