While I share your views about being amateur hours we’ve been seeing an increase in usage and releases on it. At this rate flatpak/flathub will become the defacto way of getting desktop software for Linux and it does solve a lot of annoyances and makes things more secure however it lacks features.
Even if it becomes super popular it doesn’t have enough packages. Very small amount compared to distros.
The security in theory could be good but between not knowing who packed an app and the containerization rules being configured very lax by default it’s not so great in practice.
I wish one of the serious distros experimenting with immutable distros would pick it up and start using it properly.
It’s also competing with install methods like AUR or other native stuff that’s better integrated, depending on distro.
I think it’s too early to say it will become the preferred way of getting apps, all things considered.
