The issue seems to be mostly about the support overhead from really outdated versions still shipped to the public. This seems to be a legitimate concern and why I avoid the distros in question myself.

The issue about "inferior" package managers is not that wrong as well. Version mismatches between dependencies is a big issue in development and why stuff like docker, nix and even atomic desktops are so successful.

I'm a big fan of the classical package managers, especially for my base system but the overhead on developers and packagers is definitely not negligible especially if they use pre release versions of dependencies like bottles did.

Lastly I completely get that you don't like the tone, the mint/home calendar issue was, while I get the concern, a hard read
