That is wasted $$$ and meat. It doesn't make sense to cull them as castration is extremely simple on a 4 day old piglet and not cost prohibitive. I raised hogs for a few years and castrated the males myself. I even left a couple intact and had them butchered at 6 months of age. The meat did not taste any different than the females or castrated ones.
Maybe not all producers cull them, but the companies in my state that produce piglets do cull the males.

Roast suckling piglets are a thing.
