Why are so many desktop users using old distributions?

Hey everyone,

As the author of Albert (a standalone C++ / Qt keyboard launcher), I constantly deal with a recurring headache: most of the users sit on old software. Telemetry shows that most of the users are on Ubuntu LTS or Linux Mint (based on LTS).

Flatpak is not a silver bullet, its devs explicitly told me that it is not for Albert (okay, cool). To ship recent versions of Albert for the majority of users I have to provide like 3 to 4 years backward compat. This takes a _lot_ of time.

Now I wonder: why do I have to at all? Why are most users deliberately using software that is EOL or at least quite old?

EDIT:

With EOL I mean the particular packages. E.g. Ubuntu 22.04 ships Qt 6.4 which is EOL.
