Many like myself don't like the old idea of downloading stuff that "just runs". It's too much going back to the old ways with windows where you randomly just downloaded a binary off a website and ran it.
Basically it's the equivalent of sideloading apps on mobile devices. I won't do that either unless it is required.
Now I do have one such app, in appimage which is my preference anyway. KDEnlive, which I run as an appimage Vs the Debian package only because I'm on Debian 10 on my main machine and have yet to pencil in the upgrade time.
Now, GNU Guix is interesting. Cryptographically secure and verified compilation (or pre-compilation) of source code straight from GitHub etc. Now, that will be more like it!
The man is my life lol.
I discovered GNU/Linux in school in the 90's, then as I got better access to the internet at home and Linux magazines I learned everything about RMS and GNU and the FSF.
I latched on to it all. Apart from retro systems with their various proprietary operating systems I have no time for any proprietary software if I can help it.
The Retro systems get a pass because I'm interested in old computers.
