Largest privately owned company in the world. And not being publicly listed, it is legally allowed to remain rather opaque about a lot of what it does. If you look at what it is known to do, it is basically a whole stream of shit, including the worst-welfare meat farming imaginable. Animal cruelty, deforestation, environmental degradation, exploitation of workers and consumers. You name it, Cargill is arse-deep in it and actively spreading it around as much of the globe as it can.
It is interesting how these major-evil corporations really don't like to advertise themselves. They'll advertise UPSIDE Foods of course. But you won't find their name anywhere near the marketing. They don't want people to know who they are or what they do.
