Is there a lack of rice though? I've not noticed an actual rice shortage in the rice isle?
I suppose if there is a rice shortage then Rice Krispies should probably be the first casualty. They are hardly a staple we can't live without. It's important that people in countries where rice is, to them, what bread and potatoes are to us, have enough.
But I suspect there is no actual rice shortage, they've just found they need to pay a bit more for it. So they are enshittifying Rice Krispies to keep the cost to them down, and the cost to us the same. Although they will probably still put the price up to us, and cite the higher price of rice as the reason.
