Khanacademy is a non-profit but when it comes to licensing they are closer to for-profit business licenses in that don't allow commercial derivative like wikipedia does. I love what they do though.
To be fair they may be non-profit but they still need to be able to sustain themselves financially, which means they need to operate on a commercial basis.
