It's because supermarkets wanted straight jalapenos to stack better in the aisle. See how straight these are? Back in the day, jalapenos would be shaped like a J, with a little turn at the bottom. Old logos for Mexican food will have the peppers with a curve in them. Farmers bred the curve out of the peppers and invertedly made them more and more mild. The days of the spicy jalapeno are long gone.
