This. Once you know how to use it it’s way, way more preferable than dealing with all the problems that come from how scattered the Linux ecosystem is and how little control you as a dev had about app distribution. Development and debugging gets more predictable, people can get (app-related) fixes faster, it’s hypothetically more secure (if Flatpak gets their shit together) and with the payment backend for Flatpak repos they (Gnome Foundation & KDE e.V.) work on it finally becomes properly viable to distribute paid apps. All the different hacky ways that are currently circulating (which are often outdated, only work on certain distros etc.) to offer paid applications are honestly obnoxious and expensive to maintain. Not to mention Flatpaks work great on immutable distros.

Just hope they gonna moderate things properly. Flathub & perhaps a few others have to place themselves as the de-facto standard marketplace to define and uphold all the important values the Linux community is organized around once it gets commercial. Not to do so would be a phenomenal mistake and end up in enshittification once the tech bros start targeting Linux.

So yeah, Flatpaks, Snaps and (maybe) AppImages are probably the future for most common end-user distros. Sorry for the small tangent.
