Same thing for myself, I really enjoyed the learning experience from Arch, but one day I updated my distro and after a reboot the entire thing became unbootable.

Undeterred, I downloaded the latest ISO of Arch, reinstalled and updated it. Again unbootable. So rather than provide a working latest ISO that resolved a breaking glibc change they had introduced, there was a poorly communicated and (what I considered) fairly unclear set steps to upgrade the OS. I gave them a go, still broke.

I wasn't even that mad, but at that point I realised it just wasn't the OS for me.
