It shouldn't be a legal problem. It's an additional restriction
added on top of the GPL license, crafted specifically because of the
sensitivity of this matter. I would suspect that other projects
would in turn adopt our language or language similar to ours.

Please explain to me why we need approval for our license mods from
OSI or FSF, particularly when we are adding restrictions, not
removing them.

Thanks.
