His tone doesn't even come off even as just barely smug.

My take has been people who work with code build up a view of copyright that is completely biased by the way open source model works. A model where sharing everything benefits your peers, because most people using open source will generally make their living off of products or services that are built using those tools.

The end result of photography is not a tool, it is an original creative work that is how professional photogrpahers make their living. Besides the very limited scope of fair use there is no general benefit for the community to be able to freely use the creative works of others who have licensed that work as All Rights Reserved other than to be a cheapskate.
