I've been using Manjaro for three years without issue. What gives?

Isn't Manjaro the distro that constantly fails to renew their SSL certificates, pushes security updates way too late, and distributed software that brought down the AUR a couple of times?

I have never used it myself, but from everything I've heard about it I'm kind of surprised how popular it is.

'AUR' = Arch User Repository on Manjaro. Non-Manjaro users won't know that acronym.

I'll bite. Why?
