Just go through F-Droid or Flathub and look at the long list of apps that haven’t been updated in years.

“not updated in years” didn’t used to be considered a bad thing. Why is it one now?

If something works well for me as it is and runs locally in a way that doesn’t open itself up to remote exploits, I don’t necessarily need it to keep changing all the time. Even if it would be nice if it had more features, the software works fine for me as it is. I don’t need those updates now or this year.

The only true “need” is that it doesn’t stop working for me when the various platforms or compilers change. I used to use a Python2 program, and I could keep using it for about a decade after its last update, but eventually I did need to move past it because Python3 had long since replaced it and distros stopped shipping Python2. A year or two of no updates it’s nothing.
