From what I remember they were using GNOME for pop os with some custom addons they had made (for example a tiling addon). GNOME updates will sometimes break addons and I think the pop os people got tired of this.
I actually really liked the addon as it would help you have a workflow closer to a tiling window manager.
So they are creating a DE with the features they think are important (tiling, performance, others) in mind from the start. I like the idea of this as I don’t want to commit to installing 100’s of tools for a tiling window manager like hyprland but I do want the benefits of tiling.
Also it’s written in rust which implies performance and security.
The only annoyance is that after an update by bluetooth controller gets disconnected.
