The CC-BY 4.0 license is 1,958 words.
As I understand it, the MIT license is functionally equivalent to CC-BY: it established that you can do whatever with the published work, as long as you give credit.
But the MIT license is just 162 words, most of which are in the disclaimer. The ISC license, which should be functionally equivalent to the MIT license, is even shorter: just 111 words.
Why is the CC-BY so much longer than the MIT or ISC license, even though it offers the same conditions? Or this question could also be reversed: why are the MIT/ISC licenses so short compared to the CC-BY license?
