From a tech talk about the history of JSON
(Note: Douglas Crockford put the following clause in the JSON license “The Software should be used for Good, not Evil.”)
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 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!”
