Because the DFSG say that the license must allow distribution of modified
works under the same terms as the original one.
However, this one forces modified works to be in the Public Domain, which
is nowhere near the terms of the original work.
Moreover, forced distribution of modified versions is considered non-free
(one should be allowed to create private modifications).
