that was fun
But this was late in 2002, we’d just started the War On Terror, and we were going after the evil-doers with the President, and the Vice-President, and I felt like I need to do my part.
[laughter]
So I added one more line to my license, which was: “The Software should be used for Good, not Evil.” I thought I’d done my job. About once a year I’ll get a letter from a crank who says: “I should have a right to use it for evil!”
[laughter]
“I’m not going to use it until you change your license!” Or they’ll write to me and say: “How do I know if it’s evil or not? I don’t think it’s evil, but someone else might think it’s evil, so I’m not going to use it.” Great, it’s working. My license works, I’m stopping the evil doers!
Audience member: If you ask for a separate license, can you use it for evil?
Douglas: That’s an interesting point. Also about once a year, I get a letter from a lawyer, every year a different lawyer, at a company – I don’t want to embarrass the company by saying their name, so I’ll just say their initials – IBM…
[laughter]
…saying that they want to use something I wrote. Because I put this on everything I write, now. They want to use something that I wrote in something that they wrote, and they were pretty sure they weren’t going to use it for evil, but they couldn’t say for sure about their customers. So could I give them a special license for that?
Of course. So I wrote back – this happened literally two weeks ago – “I give permission for IBM, its customers, partners, and minions, to use JSLint for evil.”
[laughter and applause]And the attorney wrote back and said: “Thanks very much, Douglas!”
