Nothing crazy about it, the regulations mean that unless it has been properly tested for effectiveness and safety as a pesticide then you can't sell it as such and rightly so in my view. Do we want another DDT disaster from poorly tested pesticides? Look at the controversy over neonicotinoids.
There is nothing to stop you putting your own grounds or any one else's on your garden as a mulch or soil conditioner. It won't stop slugs though, for that apparently you need to use the coffee you made with the grounds. I put ours in the compost bin.
