It's still in use today, but the insulation is frayed. A fire occurs. The homeowner sues. Of course not. You always sold cords that were state of the art.
Homeowners have always known frayed cords are potential hazards.
And, when better cords were designed, you put them on the market. You would be shocked that anyone could believe you should be held responsible today for the deteriorated condition of the product you sold 70 years ago. Never mind that you have been researching and developing non-lead paints and pigments and actively promoting them for 80 years. And never mind that the U.S. Government recommended using lead paint for residential surfaces for decades after you developed alternative pigments that offered consumers a wide choice. And never mind that Environmental Protection Agency and all public health authorities agree old lead paint is usually a hazard only when it has not been maintained.
