It makes sense from the business’s perspective - they want a reliable way to keep funding development.

A flat fee made sense in the days when they “finished” software and then sold physical media in stores. They did the work. They’re done. They set a price and sold it in stores.

But now we’re in this weird hybrid scenario that I hate. I expect security updates for something I “bought” (especially if it’s something connected to the internet), and I understand developers need to get paid to do that. But at the same time, I just want the software I bought. I don’t really want to keep paying over and over because the developer wants to keep adding in features that weren’t there when I bought it.
