That is true, but it is harder and harder to see why social engineering will not happen. All it takes is for a page from somewhere like 22.214.171.124:9012 claiming that you can do some interesting stuff (e.g., free access to porn) by installing their .deb or .rpm, and tell their users to just download their file and say "sudo dpkg -i interesting.deb" or "sudo rpm -i interesting.rpm". Voila, a whole bunch of clueless users will join their botnet. And their naiveness will tell them to just run "sudo dpkg -r interesting" or "sudo rpm -e interesting" to deal with the problem, and their package will be successfully cleaned up, only that their ls, rm, or even dpkg/rpm are already replaced by something downloaded from the web.
Ease of use and security should always go together. The current problem of the whole industry is that they don't. The public directly react to ease of use, they don't react to security, so the producers of software are geared towards creating software that are easy to use and compromise. If we start from having "must be secure" as one of our top priority, we will instead install every package in a sandbox, and have dpkg/rpm manage the external interface of the sandboxes, and have SELinux to make sure that the dpkg/rpm database as well as their binaries and other supporting files can only be modified by dpkg/rpm itself or in recovery mode. This is never done.
Counting on education is dangerous too. With the Internet/computer users doubling every few years, it means there are always half the users that have less than a few years experience with Internet/computers.
Perhaps it should be time to start something new, making use of all the fancy security features available, to make sure we have a "easy to use *and* secure" system to offer to the naive mass.
