It depends, what are you charging for the new features in the update/version? Twenty years ago, you'd put out a new version and I could go find what new features it had and decide for myself whether those were worth the price you ask to get them. If the answer is yes, I pay and I get the new features. If the answer is no, I don't pay and I keep using the program I already bought.

Why do you think the company is automatically entitlted to rent seeking and the removal of user choice just because they tweaked the ui?
