I disagree. Maybe it seems great if you're used to Windows or Mac, where it has always been normal to download files from 50 different websites and run them. No GPG keys, no trust, just run it. I've been using xubuntu for years, and have gotten used to having the command 'apt-get install <whatever>' install an app that integrate with the desktop by default, and a single command to upgrade all of my shit. Suddenly, because application packaging is old and boring, I have to care about some file I'm downloading and from some website. And then I have to install some other hack to properly integrate "images" into my desktop (which doesn't always work, so you create an issue on the hack project and the maintainer bitches about 'badly made AppImages') ...

Next thing you'll be telling me that I should be installing antivirus to make sure the plethora of downloaded files don't contain malware.

And if I don't bookmark all the sites where I'm supposed to get these images, I have to hunt them all down again. And if I don't bother doing that I'm running old versions of everything.

Screw all of that and give me my apt-get install / upgrade.

For the two AppImages I am forced to use, I actually ended up writing a bash script to download them, mount them and build a .deb file that does the desktop integration. Then I push the .deb to my own repo, so apt-get install/upgrade works across all my machines again.
