I'm not the one who hates flatpak, but I will point you to this comment a little further up: https://news.ycombinator.com/item?id=48435993

Flatpak serves a need, there are plenty of users who like it and there are probably even more who just use it without thinking much about it. Personally, I like it for a few reasons: - Being able to install something dependency-heavy with just one package - Sandboxing - Getting a newer package than what my distro provides - Being able to update apps independently of the rest of the OS - Being able to easily install apps that my distro doesn't provide

The people who hate it, especially without giving a reason, are largely irrelevant when flatpak is filling a need for so many other people. Design for the people who are using and who like your product. Make adjustments based on their feedback. Ignore the people who just make noise.

It's superfluous, goes against unix philosophy, solves problems that don't exist in the most obnoxious ways possible, and your distro packager is certainly better.

Not the person who wrote that but i also avoid anything related to Flatpak. The reason is that it adds a lot of extra friction to anything it touches (despite what its proponents may claim), apps ignore various settings, it wastes disk space with pointless duplication and a bunch of other issues i do not remember right now (it isn't like i write those down - i just sometimes decide to try it for something exactly because i forgot all the issues i faced and somehow someone convinced me things aren't as i remember, then recoil in horror afterwards as it turns out things are as i vaguely remember -- of course the main thing i always remember is the distaste i have for the thing, not the individual microdetails that led to the distaste).

Ultimately if something isn't in my distro's repository, i try to compile it from source and if that isn't available, i just use something else.
