I read in Ubuntu Unleashed that Ubuntu takes a middle of the road approach and does include some proprietary software (and copywritten, ect), but they give open source the preference....I just noticed that some very important ones are missing even without suitable alternatives.
I think the best solution would be if the restricted extras included Medibuntu and not just what is currently in there, and then Ubuntu is off the hook.
Everyone who wants to watch DVDs installs medibuntu anyway, and its rediculous that people should have to pay for the right to use their hardware for what they want to use it for........but lets make it just a little easier for the noobs.
Ubuntu is already not fully open source.
It should at least be included in the DVD, or ask you if you want to install it when you get to an Internet connection.
