But they won't and they don't - why?

Corporations (and by extension, lobbyists for said industries dominated by said corporations) don't think. They only care about speaking to their customer base to keep them coming back and plunking down money for their products.

Corporations aren't sentient, sapient beings; they aren't alive and don't think. Also corporations are not capable of caring either.

They don't care if the products have only one real purpose - to kill. They don't care how many lives it destroys.

They only are about getting as much money as possible, because that's how they survive and thrive.
