In defense of Ubuntu

"Can you point me to the part of Ubuntu that adds medibuntu to your sources.list
automatically?"

There is none which is my point. The legal risk for Canonical in pointing to medubuntu is
similar to the one for Red Hat if it directs users to Livna repository. The difference however
is that Canonical can afford to point people to patent encumbered and proprietary codecs while
Red Hat can't and therefore the solutions offered are completely different.People who argue
that Fedora (and by extension Red Hat) should point to Livna repository are not considering
the legal issues that make it not worth taking the risk. 

The legality of proprietary kernel drivers is certainly a gray area too. So there is both
philosophical as well as legal issues involved in these cases. Keeping that in mind helps.
