Why does the stuff they upload to YouTube's content violation detector include public domain content? It doesn't have to be, and shouldn't be, exactly the same as what they broadcast.
Exactly - publishers shouldn't upload and claim content with public domain footage in it; they should specifically remove any videos with content not originally produced by the TV station from the CID system. But that takes work, and generally people just shovel content from TV -> Web, let CID make the decisions, and move on. It's one mouse click to turn off CID matching, really easy.
