@miss_rodent Multiple distros means multiple platforms. Multiple platforms means multiple dev targets. Multiple dev targets means that developing for "Linux" is, at minimum, *many dozens of times more expensive* than developing for macOS, or Windows, or the web.
@glyph @miss_rodent But things like Flatpak exist.
@cthos @miss_rodent do they? experts seem to disagree
@glyph @miss_rodent I mean, I run several different distros across several different pieces of hardware, with different desktop environments and I can install Flatpaks on all of them, so yes?

@glyph @miss_rodent The list includes but is not limited to:
- Manjaro on a 2015 Macbook Air 11" with XFCE
- Bazzite on a Framework 13" with KDE
- ZorinOS on Starlabs Starlite (which IIRC is highly skinned GNOME)
- Vanilla Ubuntu on a weirdo 10" tablet PC thingie from Chuwi (Required some config to enable because Ubuntu really loves snaps and they shouldn't)

And all my applications just work.

@cthos @miss_rodent FWIW it's not *impossible* for this to work, but it is wildly beyond *cost-effective* for most ISVs

@glyph @miss_rodent I mean, I regularly come across Flatpak wrappers around software that the maintainers did not themselves package that also just works and is maintained by one person occasinally running a CI script though so I don't think this is necessarily true for all applications.

Also RE: filesystem permissions, it's now extremely rare that I have to fire up flatseal and make any changes at all for my normal software.

@cthos @miss_rodent I think I do have some nuanced structural critique of flatpak that I sadly don’t have time to get into right now, but if I am being honest most of my systems have a weird quirk where user data lives outside home directories on external media and this causes flatpak’s weird slightly-wrong but makes-things-mostly-work heuristics absolutely violently explode in ways which cause huge issues that contributes to an overall *immediate* negative impression
@glyph Now, imagine that we get the One And Only Distro.
Except its gatekeepers decide that this setup is weird and unsupported. You are not allowed to do things this way.
