I’ve always said this about software. Let me license a specific version, with free minor updates until the next major release.
If the new version has something I need/want, I may be willing to buy it again.
I use lots of old software, on my PC and my phone. It works, why do I need the new version? And some, the new version sucks so bad I refuse to upgrade (FolderSync on Android, for example).
