In arguing against it, [[Richard Stallman]] has stated that he counted 75 such acknowledgments in a 1997 version of [[NetBSD]].<ref name="GNU" /> In addition, the clause presented a legal problem for those wishing to publish BSD-licensed software which relies upon separate programs using the [[GNU General Public License|GNU GPL]]: the advertising clause is [[License compatibility|incompatible]] with the GPL, which does not allow the addition of restrictions beyond those it already imposes; because of this, the GPL's publisher, the [[Free Software Foundation]], recommends developers not use the license, though it states there is no reason not to use software already using it.<ref name="FSF-OriginalBSD" /> |
