I suggest to have the factual copyright discussion on Wikimedia Commons.
Otherwise it is kind of pointless, because the admins still will not see it :)
I don't know appropriate page in Commons for such discussion. If you know please help,
https://commons.wikimedia.org/wiki/Commons:Village_pump/Copyright would have been a good start. The DR Tomasz linked is now.
Andrij: I would also suggest to not call this kind of good faith vandalism
- that is highly inappropriate.
It is exactly appropriate. Deletion without any attempt to talk with uploader is a vandalism, especially during the contest.
(Leaving FoP issues aside; no, it is not.)
