unwilling/unable to make their works free then they shouldn't be including
any CC-BY-SA content.  If content creators don't want that outcome, they
should be using CC-BY rather than CC-BY-SA.

Having said that, I generally agree that it is functionally impossible to
reach an agreement on this matter, and it seems likely that the only way to
make progress is to create a CC-BY-SA-Strong to satisfy those of us who
believe that copyleft really should be viral.
