Because it sucks? 🙃

Like, seriously, Manjaro had so many problems already that were completely preventable, makes stupid mistakes, bloats itself up with nonsense and provides no stability improvement over Arch whatsoever (which is a bad thing). On the contrary, it apparently even introduces additional bugs.

I'm not surprised they accidentally DDoS'ed the AUR, given they also have a docker script that spins up every single time an image is downloaded to push a change to git to increment a counter. Every. Single. Time. A full docker container. From scratch.

I'd only ever recommend Manjaro to people I really don't like.
