Copyleft is a term with a very specific meaning.
It applies to a license which does not allow
the community to change the license on derivatives.
Alice releases a work under the YAL license.
YAL says all derivatives must be under a YAL license.
THerefore YAL is a copyleft license.
NC is not copyleft because Alice could create an NC
work, then Bob could create a derivative and license
it NC-ND-BY or something.
NC-SA is copyleft, but only because the SA part is copyleft.
And then there's the distinction of whether NC-SA is "Free"
or not, which is independed of whether it's a copyleft license,
but we already covered that.
