Subscription based software has only become a thing within the last 5 years or so. Prior to that you paid a one time fee for apps or software. Then the companies became greedy.

I've been using AutoCad since the late 80's and Photoshop since the early 90s. Initially you paid a one time fee for the software. If you wanted to pay for the newest version great. If you wanted to wait a few releases and upgrade great. I would often skip 2-3 upgrades of the software and upgrade at my leisure. Point being these software companies did not go out of business just because it wasn't subscription based. They got greedy.

I have a weather radar app on my phone. I paid a one time fee so I don't have to deal with ads. If they go to a subscription based program I'm out.
