That would make it very non-free software. And that is what ubuntu is trying to not be.

You can sell free software. It's free as in freedom not as in free beer.

If you're referring to the price, well, that was covered by another comment.

Ubuntu's full of non-free software and binary blobs. This is why it pretty much works out of the box. There's little fucking around with drivers, non-free codecs, etc.

In any event, adding non-free "premium" features doesn't make the operating system itself any less free.
