Yeah. Scientists nowadays don't work with tissues to produce 'nutrient' foods. (Points to Monsanto specifically) This meat made out of human poop already passed the smell and taste tests... It's all about convincing the masses to consume it.. Nutrients aren't important.

Scientists and food supply chains are different things.
I've also seen some of the studies these guys do, and most of the brands that contain 'other than labeled' are brands that most people have never heard of, and not what most people grab off the shelf.
The irony in that study you post is that it confirms quite the opposite trend than what you suggest. Local stores and other small processing/packaging businesses are more likely to use deceptive marketing than larger suppliers. Sushi store can't afford tuna? They'll buy something else and run a special. Massive tuna cannery can't meet quote for tuna? Out-bid your competitors for tuna supply contracts and raise the MSRP of your tuna cans, if necessary (where are your competitors going to get their tuna?)
That said, I can see this being used as an animal feed. It might work out pretty well in that regard.
Though I would still be for treating it to use as fertilizer before processing it as a protein source.
