I have a much easier time using REAPER rather than Ardour.

Nobara. But I’ve had them work on nobara before

Okular can digitally sign

Fitgirl installers just crash on me 🤷‍♂️

True, my bad

Okular, comes with Linux

In much the way I am aware of the Windows store: I avoid it and work to get the software directly from the source.

That is not the way things work on Linux - the repos essentially are the source. It is intended for apps to be packaged and distributed through official repos precisely to avoid the issues you listed, which are more often issues of downloading from sites. Package managers take care of incompatible versions and conflicts. That’s definitely a Windows bias my friend :P

80% of the reason to move to Linux is hating Windows, so yeah

I ask this with full sincerity - are you unaware of the package manager?

Compartmentalisation helps

If no one actually knows the plan other than the guy in charge, no one can leak the plan:

An example of compartmentalization was the Manhattan Project. Personnel at Oak Ridge constructed and operated centrifuges to isolate uranium-235 from naturally occurring uranium, but most did not know exactly what they were doing. Those that knew did not know why they were doing it. Parts of the weapon were separately designed by teams who did not know how the parts interacted.

My point is that old doesn’t automatically mean incompatible. Especially with stuff like games.

Because you’re mistaken about how compatibility works

Bashing Ubuntu is getting really fucking old.
