Be careful who you trust when installing software is a fine thing to teach. But that doesn't mean the only people you can trust are Linux distro packagers.
I think it has a lot to do with "curl|bash". Cut&paste a curl|bash command-line disables all inherent mechanisms and stumbling blocks that would ensure properly ensuring trust. It was basically invented to make it easy to install software by circumventing all protection a Linux distribution would traditionally provide. It also eliminates all possibility for independent verification about what was installed or done on the machine.
