The "shit burgers" are troublesome, but I don't care even a little bit about using shit for fertilizer or fish food. Folks have been using shit for fertilizer for millennia before the production of "synthetic" fertilizer by petrocompanies. even that "synthetic" fertilizer is just shit - it's just millions of years old shit that was deposited by the marine life that went on to become the oil from whence the gasoline to run your car is derived. It's still shit, just old shit, and they use it every day to fertilize fields to get those tomatoes to your table.
Fertilizing with shit is no worse than using compost - I wouldn't want to eat a mouthful of either shit OR compost, which is just rotted garbage - but plants seem to eat it right up.
As far as the tilapia fish goes, that's not really a problem for me, either. I've been eating catfish for decades, and it hasn't harmed me. Catfish are "garbage" fish too. They live on the bottom and, as "bottom feeders", eat whatever they find on the bottom - and that includes a fair amount of the shit that goes into a stream, or is produced there by stuff that lives in the stream. By the time I eat one, it's not shit any more, it's fish. You can even buy tiny catfish to keep the fish shit cleaned off the bottom of your aquarium.
You eat beef, and beef is fed on grain and grass, and that grain and grass is fed on... shit, and rotted stuff. Yet eating a black angus doesn't seem to bother anyone other than vegetarians.
You're born, you live, you die, and then you rot or are eaten - in which case you become shit - and as either rotted biomatter or shit, your molecules are taken up to live again in some other organism, which suffers the same fate - wash, rinse, repeat, over and over forever.
