I’ve used flatpak for a while because it’s the default ob Fedoras GUI Software Center, but I’ve recently switched back to dnf and native packages where I can.
The thing is, that I have a shitty 500GB SSD with a shitty 50Mbit Internet connection (which is closer to 30Mbit because my house still has lead cables instead of copper). So downloading 300+ MB of libraries for a 2MB Program is just not feasible for me.
