Well we could discuss  if in general CC-by-SA 2.0 is at all suitable as 
a replacement for contributor terms, but naturally for example the "sui 
generis" database rights are one of the problematic issues (being the 
most likely IPR that large contributors could own).

And we know that they "cheated" .... that particular horse has really 
been flogged to death (and I believe that they did simply change the 
text you had to agree to on saving an article to include CC-by-SA for 
the unwashed masses). OSM is very different than Wikipedia in many 
areas, for example Wikipedia doesn't really distribute its data for use 
in other projects (commercial or other)  and in so far doesn't have as 
large responsibility towards downstream data users as OSM has.
