[Trisquel-users] Re : [OT] Charging for source code

[magicbanana]

It is evil (like any proprietary program) but yes, it is possible to  
encounter binaries under a proprietary license even if its source code (but  
does it really match?) is distributed under a free software license.

The author can always do that. Someone who is not the author of the source  
code can do that as well if she received the code under the terms of a free  
software license.
