And this one? If that's right why I'm working on bugfix now? Is it because of the subscription model? If it was one time fee, am I going to just ignore the bugfix requests?
Me, I guess. I've released MacOS apps for free and never felt any expectation to provide indefinite support. They do what they are supposed to do and people still use them.
Why do you keep saying that "support forever" is the default here? Nobody would expect that except if you were releasing under a subscription model.
Plus, this app doesn't need support. Come on.
