In Facebook's terms of use there is a claim that Facebook can
sublicence the content, while in CC-BY-SA there is a clause cleary
stated that you cannot sublicence the content but only release it
under CC-BY-SA or compatible licence. IMHO just because of this reason
one cannot upload CC-BY-SA licenced pictures to FB without direct
copyright owner's agreement. When uploading antything to Facebook you
agree on their terms of use, which means that the content is published
under their licence, not CC-BY-SA even if you claim that you release
under CC-BY-SA. Moreover - at least in case of our Polish part of WLM
regulations we assure uploaders that we will re-use the pictures under
CC-BY-SA conditions only.
Of course the owner of the copyright can do whatever he/she wants with
their own works as CC-BY-SA is non-exlusive licence. Anyway, I think
that danger that any WLM photographer may sue us is close to 0, but
there are people who hate FB - so they can make a noise about it in
Commons' discussion pages or e-mail lists.
