RPM based distros (Score 0, Flamebait)

Wow, look at his comparison charts in the package management section and you will find that a huge majority of systems are using rpm. A couple of deb, and a couple of tar.gz systems and all of the rest are rpm based. So why is that the (arguably) worst package management system ever is so predominately used? SuSE is the only company I have seen that can make it work well. Having said that, SuSE would be my main distro if they would switch to the deb format. As it is now, I will take Debian or Slack over any of the others simply for their non-use of rpms. Who knows, maybe I have spent too much time in dependancy hell.
