in case you are trolling, kde can license Qt code as lgpl or gpl or gpl2 or whatever free license they like so i can't see your point [did you read the actual agreement?]
KDE can not relicense Qt. KDE can relicense Qt Free Edition. This is very important to understand. Threatening Digia to keep doing Qt Free Edition releases by keeping the license is not very powerfull KDE can only threat Digia by releaseing a non-free but liberal licensed version of Qt Free edition.
So if Digia goes non-free so kan KDE. How can this not be seen as holding to guns against freedom?
