Reminds me of Doug Crockford's "Don't use this shit for evil, yo" clause for JSON's licensing which automatically invalidated it as a real open source license.

I forget who but there was a famous programmer who added a clause to his open source stuff that it "cannot be used by the Israeli government" (and their allies? I can't remember.)
And of course this makes me think of TempleOS, the best anti-semitic OS ever.
