Spot on. If I didn't care what restrictions other people put on my work, I
would put it in the public domain, or use the cc-by license.

Doing derivative works from cc-sa as cc-sa-nc defeats the entire 'alike'
part of 'share alike'.

It also worries me how easily cc-sa community projects could be 'polluted'
by extra unwanted restrictions if the general impression is that all cc
licenses can be mixed. A lot of people do not care much about the small
print, just about 'getting things done', and it is already hard enough to
get people to understand what is a derivative work.
