I don't think you understand. The restriction is on the removal of the
additional permissions. In your example, the restriction is that if I do not
wish to grant those additional permissions to Jim *, then I am still forced
to do so. To quote the GPL (from memory), "You may not impose any further
restrictions on the recipients' exercise of the rights granted herein."

Exactly! But what if I don't want to do that? The restriction is forcing
others to use license terms that are not in the GNU General Public License.

Section 2 sayeth:
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
If you cannot license them under the same terms for any reason, whatever it
might be, then sections 4, 5, 6, and 7 apply. If that reason is because
there is an exception that cannot be removed, then it would still apply. The
reason that many exceptions (including the one recommended by the FSF) allow
removal of the exception, is so that they are under the same license.

I have no idea about Ada, so I cannot comment on this.
