> But I admit I don't really know how AUR works

It's basically GitHub (in terms of "User's generated content") but tailored and specific to Arch/Arch-derived distributions. Packages have owners, but everything is very "freeform" in general on the AUR. It wasn't uncommon you could be added as a maintainer by just sending a mail to the current maintainer, since it's basically "Hey let me contribute to your repository" (simplified), today people keep track a bit better and avoided that I've seen. But still, it's on a individual basis.

Just like GitHub, AUR is completely devoid of peer-reviews, users uploads their own PKGBUILD and share with others, and the expectation is that users review stuff before they install it, just like on GitHub, or just like on the internet in general.

Yeah, the AUR is basically build scripts for github repos or a link to someones pre-built binary. It suffers from all the same problems that the underlying infrastructure suffers from. You could very easily argue that since github/npm/cargo/<your package manager of choice> has a supply chain issue so does the AUR.
