It's my understanding that Mazz did not "turn to the BBC"- she reported the person who was selling her patterns on ebay to TPTB at ebay, and apparently that unethical ebay seller reported her to the BBC. Her first contact with the BBC was the c&d from them.

She promptly removed the patterns, came to the communities and calmly but regretfully explained to other users why she was removing them.

Other users strongly encouraged- one could go so far as to say begged- her to contact the Open Rights Group to ask them to fight it.
