With the Steam Frame and Steam Machine launching with SteamOS Linux this year, we’re going to again see a nice boost for Flatpaks and desktop Linux overall.
Linux has, historically, been quite messy when it comes to software distribution. We have various distribution-specific packaging formats like .deb (Debian / Ubuntu), .rpm (Fedora) and the list just goes on and on. Canonical also went their own way with Ubuntu for the likes of Snap, but the real winner is going to end up being Flatpak and the main Flathub store.
Possibly, but it’s being marketed to the console crowd. They’re not going to get big numbers from people looking for a PC. It should at least be profitable for Valve, but it’s a damn shame it had to release when hardware pricing is so messed up.
