[Trisquel-users] Re : What do you think of Steam coming to Gnu/Linux.

I am not a native English speaker but the first definition of "permissive" in  
Dictionary.com perfectly matches licenses such as the BSD:
tolerant of something, as social behavior or linguistic usage, that others  
might disapprove or forbid.
In our case, the something is "turning the application proprietary" and  
others (copylefted licenses such as the GPL) forbids it.
