Thanks for the reply, MH. I'm very well aware of the legal issues related to proprietary formats. But I don't think this list is the right place to discuss specific legal/patent issues? Or is it?
In general, most big, international Linux distros also don't pay any software licensing fees and therefore they also don't distribute proprietary software. But they do make it considerably easier than openSUSE does to install such software when the user needs/wants it. In some cases, considerably better defaults could be configured using the available open source software that could help some users to not recur to a proprietary/licensed alternative.
