As you may know, I am the creator and lead developer of Hyprland and the entire ecosystem around it. You might say I’m biased, but I try to approach this from a quite objective side.
Cosmic is not my direct competitor - Hyprland is a compositor for advanced users, Cosmic is (what it’s meant to be, at least) a user-friendly DE.
The lady doth protest too much, methinks. Cosmic has Wayland and tiling, it has the backing of a profitable company, and he’s very obviously salty about it.
