I've spent a good chunk of the day reading through the first 31 questions; the comments on meta about those questions, and the responses proposed by Dimi and others at
http://youcan.fixcopyright.eu/en/full/?guide=wikimedia
All the comments essentially agree, with only some small variations.
Since we don't have any serious splits of opinion, I think the idea of a
combined answer that represents this as the opinion of the Foundation makes sense. (Not clear to what extent we should also represent this as the opinion of Wikimedians - opinions welcome on that.)
With that goal in mind, I've drafted proposed answers to each question, which incorporate comments from (among others) Seb35, Deryck C., Sapfan, NaBUru38, Aktron, and Kaldari.
