> Maintenance should not be expected for free.

Users who purchase an app definitely expect there to be maintenance on the app. This is because we know no one tests their app to 100% perfection.

If I knew that the app I get at the time I pay is all I get with no future updates, not even bug fixes, then I'd wait several months to make sure no one else finds any bugs before I ever dare to buy the app. So developers give users the expectation of future updates and fixes to assuage user fears so that they actually buy the 1.0 release and give the developers some money to keep living on.
