When I put the reference implementation onto the website I needed to

put a software license on it.

And I looked at all the licenses that were available, and there were a lot

of them. And I decided that the one I liked the best was the MIT License,

which was a notice that you would put on your source and it would say,

"you're allowed to use this for any purpose you want, just leave the

notice in the source and don't sue me."

I love that license.  It's really good.

But this was late in 2002, you know, we'd just started the war on terror,

and, you know, we were going after the evildoers with the president and

the vice president, and I felt like, "I need to do my part".

So I added one more line to my license, was that, "the Software shall

be used for Good, not Evil."  And thought: I've 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! I'm not gonna 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 gonna use it."

Great. It's working. My license works. I'm stopping the evildoers.

...

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," saying that

they want to use something that I wrote, 'cause I put this on everything

I write now. They want to use something that I wrote and something that

they wrote and they're pretty sure they weren't gonna use it for evil,

but they couldn't say for sure about their customers. So, could I give

them a special license for that?

So, of course!

So I wrote back---this happened literally two weeks ago---I said, "I

give permission to IBM, its customers, partners, and minions, to use

JSLint for evil."

And the attorney wrote back and said, "Thanks very much, Douglas!"
