What is fascinating about the description there is that IBM hasn't just asked once - they've asked many times.

I'd be willing to bet that the cause is that IBM's lawyers are aware that the most famous act of evil in the 20th century was committed by an IBM client, using IBM equipment. No joke, that was how the Nazis kept track of the Jews. And I'd be willing to bet that there are a lot of random dictators today who are using IBM software to keep tabs on their populations as well.

So while the IBM license exemption sounds silly and amusing, there is a very serious point behind it.

Incidentally this clause makes jsmin both not open source (discriminates against fields of endeavor) and also puts it in Debian non-free (same reason).
