What is the One True License?
I prefer the MIT license and almost everything we open source at GitHub
carries this license. I love this license for several reasons:
* It's short. Anyone can read this license and understand exactly what it
means without wasting a bunch of money consulting high-octane lawyers.
* Enough protection is offered to be relatively sure you won't sue me if
something goes wrong when you use my code.
* Everyone understands the legal implications of the MIT license. Weird
licenses like the WTFPL and the Beer license pretend to be the "ultimate in
free licenses" but utterly fail at this goal. These fringe licenses are too
vague and unenforceable to be acceptable for use in some companies.
On the other side, the GPL is too restrictive and dogmatic to be usable in
many cases. I want everyone to benefit from my code. Everyone. That's what
Open should mean, and that's what Free should mean.
