I remember the outcome and I think it was an unfortunate one.

I agree with Ben on the importance of the source availability
requirement for a license (such as CC-by-sa) that claims to implement a
copyleft mechanism.
See for instance this old reply of mine:

I am convinced that the definition of source found in the GNU GPL is
adequate for any type of work.
I wrote an essay about this definition of source. For those who are
