I believe it is the person who sets up the shot is the one who gets copyright. So if you set up a group photo, ask a passer by to push the button so you can also be in the photo, the copyright doesn't suddenly belong to the random passer by.
So really it's an argument of did the photographer set up the photo and the monkey just ended up pushing the button.
So if I just make a monkey click "download" on a torrent site it becomes legal?
I don't get the maths:
£2k in the first year (2012), then £10k estimate to the present day (2-3 years).
Why would he estimate that he would have a sustained revenue increase of 50%+ from a photo?
Maybe its to do with the legal fees needed to take wikipeida to court...
Don't think its the monkies' copyright, mainly because its not human.
