When you’re maintaining a product that is based on linux, you’re surely qualified to port that thing to your platform yourself.
Open source developers are thanklessly giving away their work for free already, and for the many things where there’s just a github page it is just a one man show run in spare time. Don’t demand them to give away even more of their time to cater for whatever distro you’re using, just because you are not willing to invest the time to learn how linux works and also not willing to give a way a few megabytes for the dependencies they’re developing against.
All the discussions about things like distrobox and flatpak where linux novices express their dissatisfaction due to increased disk space are laughable. In the linux universe sole users have no power in deciding what goes, they do not pay anything and at worst pollute the bug tracker. Developers are what make up the linux universe, and what appeals to them is what is going to happen. Flatpak is a much more pleasant experience to develop for than a gazillion distros, hence this is where it is going, end of story. As a user either be happy with wherever the linux rollercoaster goes, or - if you want to see change- step up and contribute.
