A free program must offer the four freedoms to any user that obtains a |
| 124 |
|
copy of the software, provided the user has complied thus far with the |
| 125 |
|
conditions of the free license covering the software. Putting some of |
| 126 |
|
the freedoms off limits to some users, or requiring that users pay, in |
| 127 |
|
money or in kind, to exercise them, is tantamount to not granting the |
| 128 |
|
freedoms in question, and thus renders the program nonfree. |
