Welcome to the US. You shoot somebody and they sue the gun maker, you stab somebody and they sue the knife maker, you run somebody over and they sue the car maker.
There is usually some extenuating circumstance when these cases do prevail. For instance one manufacturer was found to have such incendiary marketing around their assault rifle it had risen to the level of a "call to arms". So typically it has to be more than "We are the manufacturer"
Which case? Corporations have free speech rights. They have artistic license to advertise their product as they see fit. I don't see how that's a "call to arms" anymore than military movies are.
