I don't like the idea of them introducing any kind of sterilization agent into the water supply. That is just morally wrong. They most likely have no idea what effect that agent will have on other native species.
I like hunting hogs as much as the next guy, but I think the hog is the most robust animal in the world. They throw litters of 8 +/- twice a year and can infest an area in minimal time. I don't have a problem with someone killing a wet sow for two reasons: First the shoats will most likely survive on their own and second, those that aren't weaned will likely be adopted or eaten by another sow or hog. Its amazing how many shoats are eaten by other hogs. Just amazing...
...but, that's just my perspective.
