Mostly misdirected anger from two categories — Arch purists who balk at the notion of someone modding their beloved distro, and newbs who blame Manjaro for issues they create themselves and they would have on any Arch-based distro.
Nope not at all. The built in and by Manjaro maintained packagemanager pamac bricks systems. Has not bricked mine since i use pacman instead.
The packages are just the arch packages delayed by a few days which makes it incompatible with the (by default enabled an encouraged to use) AUR.
