+A free program must offer the four freedoms to any user that obtains a
+copy of the software, provided the user has complied thus far with the
+conditions of the free license covering the software.  Putting some of
+the freedoms off limits to some users, or requiring that users pay, in

+freedoms in question, and thus renders the program nonfree.
