I like the general idea of ongoing revenue, but I want to pay something on par with buying a full version every 3-5 years. Subscription software usually costs much more than that.
I would love for developers to stop messing with most apps.
Haha, you say this until Apple does a breaking change to the barcode library or Apple Health export and things stop working. Then you probably want them to change some stuff :)
It would be nice if OS vendors would stop breaking things, too.
This would often be a feature.
Except most app stores require future maintenance and compliance to keep publishing the app. Someone has to keep the lights on.
