In control of installing malware?
I get what you mean, but people are stupid. There needs to be guardrails to prevent these things from happening. That's why the AUR is a bad idea and it should be shut down.
You want your software to be available for a distro? Go through the proper channels. Submit it for review and get it approved. If you stop maintaining it, they remove it. Plain and simple.
That's why you don't have this problem with other distros. Arch made it too easy to download and install unverified, untested, potentially malicious software through the AUR and now every idiot that thinks they know what they're doing are infecting their systems.
