His cases that I could find are where the company republishing his photos didn't attribute them to him at all so it seems fair to sue (except when it turned out to be fair use). What is this attribution error you mentioned? CC BY-SA 3.0 is pretty onerous "You must give appropriate credit, provide a link to the license, and indicate if changes were made." All 3 things are required. Maybe every CC-BY photographer should be suing newspapers for stealing their work, shouldn't they?
