I think support is different. If you buy a game that requires a particular machine spec and OS, and then come back 10 years later with a different OS, that's not the developer failing to meet their "contract", it's you failing to run the game on a system of the required spec. Now I do think there should be a carve out in the law to explicitly allow emulation, i.e. developers should not be allowed to prevent you using emulation, so that you have a reasonable path to continue using your content in the future.
