[General] Why is that when a nefarious organisation creates a doomsday weapon or a computer chip that can break into anything, they often try to sell it to the highest bidder instead of just using it to make more money?

Maybe they don't have the desire to do the legwork. They do R&D and don't really want to bother becoming the face of terrorism that holds the UN hostage for ten billion dollars. Its a whole different sector of the evil villain industry. 

In the example of Ant-Man, Cross sold the weapon so he could continue selling the ammo for it. So its a better payout structure for someone who isn't actually focused on running the world.
