Much of the time decisions to break backwards compatibility are made to remove roadblocks in the OS development process. Keeping old software for the platform running forever has a high cost, and so I think that OS vendors wanting to limit how far back that compatibility goes is entirely reasonable. If the argument is that OS vendors should include virtualized old OS environments for compatibility with old binaries to make sure OS development remains unencumbered, I could get behind that, but in that situation App Store listings of seldom updated apps should include a highly visible indicator that it’s been many years since the last update and as such expectations of significant bug fixes and support should be tempered.
