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.)
