> This has been litigated endlessly with guns. The ceo of Smith & Wesson is not personally responsible for what people do with their guns.

This is a deflection. A human is responsible for the use of a gun. The individual/corporation ought to be responsible for the actions of their agent. If you purchase an agent from someone else it’s your responsibility according to the terms of your agreement. And, as in many other things in life, there ought to be certain rights certain parties cannot legally be allowed to sign away.
