As far as I am aware Ubuntu complies with all trademark requirements for upstream software that it packages (e.g. Firefox, and probably other 3rd party pre compiled software). For most F/OSS software they have no trademark requirements and/or registered trademarks. So in effect Ubuntu are doing the right thing (tm).
Sigh. Why is everyone so literal here. The question then is: If upstream authors are so generous not to trademark their works, and Ubuntu (attempts) to make money on their backs, why does Ubuntu not do the same for its derivative work?
