Flatpak is installed by default and used by their app store, and Firefox is packaged as a deb so you can avoid the snap.
I consider it a deshittified Ubuntu.
This is more or less what I have used Linux Mint for (their Cinnamon desktop version is pretty okay, also used the XFCE one).
Nice to have more options!
They show icons for Steam, Chrome, Firefox, Zoom, etc... Does that mean they are maintaining their own fork of those applications built for COSMIC?
The version of Chrome (for example) that Google distributes uses GTK which is GNOME, no? So I was wondering if System76 forked that and made a version that uses the COSMIC API.
