#+title: The CC BY-NC-SA license is bad, don't use it 
#+date: <2022-03-03>

The CC BY-NC-SA license permits remix, but forbids commercial use
(therefore nonfree).  It is a weird frankenstein that combines
copyleft with nonfree elements.  As a result, works under this license
will beget derived works, which will also be nonfree because of the
ShareAlike (SA).  It is a mistake by Creative Commons, which should
have not designed any noncommercial licenses, or if it really wanted
to, made noncommercial an optional clause of NoDerivative (ND)
licenses.

Please do the public a favour and don't release your work under the
NC-SA license.  If you really do not want to allow commercial use,
please use NC-ND instead to avoid nonfree derivatives.
