It has outgrown the mindset that AUR is for people who use and follow the advice of Arch Linux? Or what do you mean? What I'm describing is a workflow you can apply today, apply it equally to all packages, and it stops 99% of the hacking attempts and the remaining 1% wouldn't matter if it's via AUR, NPM or Cargo, same issues remain.
> It’s a cultural problem and your mindset is precisely why this will keep happening
I agree that "Anyone can automatically take over 100s/1000s of packages as a maintainer" is a problem, I don't agree that it's a deeper problem than that. Limit each user to be able to take over one package per month, and suddenly we get all the same benefits we have already, + we fix the current issue.
No need to trash the entire AUR when there is one specific feature broken, just fix that feature, then continue your pragmatic life as before.
> As an Arch user I’m honestly embarrassed and I’m going to be looking at distros that aren’t user hostile like this.
To be fair, if I ended up misunderstand something so deeply that I didn't realize how to actually use it, I'd be embarrassed myself as well, strong of you to at least state so publicly. I'm happy you at least figured out that Arch Linux isn't for you, and you start trying to find a distribution that fits you better, rather than going through a tough period of time trying to change something into a direction it isn't even aiming for.
