If you buy a defective product from Target would you sue the cashier? No?
But she took your money, she gave you the product, she's the seller... right? No?
This is no different. Its just that the scale is different.
Is the party store responsible if there is a mouse in your beer. No.
Is a car dealer responsible for a manufacturers defect. No.
Is your pharmacy responsible for a bad batch of viagra? No.
The fact is we have a lot of people here operating off emotional biases, focusing their hate on the big bad company and ignoring the facts. If this family had bought the device at the little mom and pop store on the corner that's been there 60 years would the same people think they should lose their business, home and life savings? Are they prepared to give up their homes if they sell an item in a garage sale that breaks? But it's ok if it's the "bad" company. This is the same reasoning that convicts innocent minorities because, 'well they look like thugs they probably did something wrong'.
