I think the situation is more complex than you're asserting. Unless a program has stopped development, it is not a product -- it is an ongoing work that's more akin to a service being provided by the developers. UI changes, bugfixes, refactors, and etc mean that existing features are not zero-cost to the developers. I understand that it's frustrating to lose niche features, but that's a symptom of other complexities, not a cause-free act of foolishness by developers.
