With MT changing its license structure, Drupal gets better (in a relative way).

Or isn't drupal getting better, even relatively because the license of Movable Type always had the option to change and become more restrictive? Was Drupal always better due to its GPLicense?

One of the best articles I read regarding non-free licenses is here. This is about the beatifull words "free enough" and the culpits that come with it.
