Enterprise distributions suck and free software rules

Now you are just being very silly. Distrowatch doesn't list several distros, for semi-arbitrary reasons. They try to make a judgement on which ones are likely to stick around and don't list all of them immediately. Some of them languish in the waiting period forever for instance. Noone claimed any of this was a conspiracy but rather that the raw count is a unreliable reference and there are significant and more important differences besides the package format and distro origin.
