Flatpaks saved my bacon when I borked my Linux work computer and didn’t have time to fix it. Spent 2 months with half my apps on Flatpak because the native ones weren’t working.
It’s also great as a developer. While I do provide x86 and arm binaries, I don’t bother distributing them in 20 different formats. The website links to Flathub, and the number of distro/Mesa specific issues has dropped to 0.
