You can also simply use Flatpak with the Freedesktop Runtime. It runs everywhere regardless of the distribution. For games Steam offers something similar with the Steam Runtimes. You simply develop for that one container and the software will still be running in 20 years. Even though, of course, making software proprietary isn’t best practice. If you make everything open source from the start the various Linux distributions and users can adapt it themselves for their distribution and eventually modernize it as well.

From the flatpak docs:

> A given branch of the Freedesktop runtime has a 2 year support period after which they are declared EOL.

EOL doesn't mean you can't install or use it anymore. It simply means you shouldn't use it anymore because security updates are no longer available. You face the same problem with Windows software that is no longer updated. The only difference is that no one tells you it's no longer supported.

If my employer would still pay me the same salary, I couldn't care less about the license. I'm all for outsourcing this problem to the package managers.
