Naopak. Problem je, ze drivery jsou dodavany v binarni forme.
Pokud je vyrobce zverejni ve zdrojacich a s prihodnou licenci,
pak jsou v naproste vetsine pripadu zacleneny do stavajicich
baliku a ty pak clovek ma integrovany ve _vsech_ aktualnich distribucich.

Problem je prave v tom, kdyz tohle vyrobce nepochopi a snazi se Linuxu
vnutit pripos*ane korporatni moresy...
