- Nokia actively lobbies in favour of Software Patents. This might not be an issue for now, but a culture clash might happen soon. Gladfully, QT is licensed with GPLv3, but yet, this can be a showstopper for both FreeQT and KDE.
- Nokia have a no Ogg, pro DRM position regarding HTML5. If they somewhat forces this to Trolltech (instead of doing the right thing, supporting Ogg, rejecting DRM), once again this can be a showstopper.
What this really means, in fact, is that this two issues concern me and a lot of others - and that they should be answered before this aquisition ends... or else there's some uneasyness Trolltech and Nokia will have to deal with.
