[modifier] Double licence : libre et propriétaire
- MySQL : MySQL ABC racheté par Sun, puis Sun racheté par Oracle
- SDL :
- SDL 1.2 sous LGPL
- SDL 1.3 passé sous LGPL+proprio : Sam Lantinga a demandé à tous les contributeurs de pouvoir changer de licence puis a fondé Galaxy Gameworks
- PyQt : GPL et proprio
- Qt : proprio, puis GPL + proprio, et finalement LGPL + proprio
[modifier] Problèmes de licence
Liste non exhaustives de problèmes liés aux licences :
- Licence Apache 2 (?)
- Le code source publié sous la version 2 de la licence Apache ne peut pas être inclus dans OpenBSD. Par conséquent, OpenBSD maintient désormais sa propre version d'Apache basée sur Apache 1.3.29. La version dans OpenBSD inclut plusieurs améliorations et corrections. (extrait de Politique de Copyright)
- Licence OSSv3 : OSSv4 passe en GPL
- Toutes les histoires de NDA, ex: Fin du support Linux des webcams Philips (Slashdot | Kernel Maintainer Kills Philips USB Camera Support)
- Pilote Wifi Atheros : code BSD passé sous GPL
- L'auteur initial du jeu Nexiuz vend le code et dit qu'il ne reversera pas les modifications à la version GPL : fork sous le nom Xonotic
Logiciels passés sous licence libre :
- Blender : suite à la faillite de la société NaN, l'auteur de Blender (Ton Roosendaal) racheta les droits d'auteur pour 10.000€ pour distribuer le code source sous licence GNU GPL
- Firefox (ex-Mozilla, ex-Netscape Communicator)
Autres :
- Xara Xtreme : libéré partiellement => échec
- NetBSD est passé de BSD 4-clauses à BSD 2-clauses
- PostgreSQL, OpenSSL, and the GPL
Autres :
- Conflit de licence :
- Violation de licence :
- gpl-violations.org : uniquement la licence GPL (GPLv2 ?)
- Première poursuite judiciaire aux États-Unis concernant une violation de la GPL (sept. 2007)
- Les auteurs d'iptable et de Busybox appellent Iliad/Free à respecter la GPL
