That is true of other Open Source licenses such as the BSD license.

The point of the GPL is that if you extend a work distributed to you
under the terms of the GPL you are obligated to distribute your
extensions only under the terms of the GPL (though you are free to not
distribute them at all).  This is not true of the BSD license: you are
free to distribute derivatives of BSD licensed software under any terms
at all.  This was routinely done: I paid $1000 for BSD-OS for my first
386-based computer.
