To be verified:
Controversial:
- Against DRM license - very vague, legally speaking, about what exactly it tries to forbid. If it forbids use even for developing DRM, bundling with DRM, etc., it is not a free content license. Legally speaking, this license uses the same definition of the law.
- IANG license - seeks to enforce lots of things that are outside of the copyright realm (like organization scheme, rights of users to have a voice in the development process, etc.)
