Arch also warns uses about AUR, use at at your own risk, and can break your system.
My approach isn't definitely not the best solution, I was saying this is only the beginning, and with other arch based distros also using AUR only gets worse, if there's any moderation and some kind of package control before publishing then when thins get real bad maybe too late and arch starts loosing users.
Now is just some packages, later could be some popular package take overs or some kinda spoofing of other packages.
I use arch BTW (since 2011), and ~~Debian~~ Armbian on Raspberry Pi, one is rock solid the other sometimes break with updates
Just the case of the packages being removed only a few hours after been published just makes my point of "trusted users" reviewing and reporting then.
And is not only an archlinux/AUR problem, the same happens with python pip, npm, dockerhub, github... With bigger popularity, bigger the target.
These days after the success of Steamdeck many users switched to Linux, and many of those started using arch or based distros like EndeavourOS because some one on reddit, YouTube or other said is the best for new hardware and you can find everything you need on AUR.
New users won't review scripts or PKGBUILD, that's gibberish, just search and install, and a few hours could be too late for some.
I don't care if Linux loses or gains popularity, but if there's no guard rails of some kind of control things could get worse, and even end AUR as it is now.
Having people control what's published or not, probably not the best solution, but leaving it as a wild west also not
