It is the same as with any product on the market. The producing company is liable, if the product causes harm when used and it is the products fault that the harm was caused. For example if lets say a TV blows up during normal usage. This is fist of all liability for damages. A criminal charge only happens if it can be shown, that there was any active wrongdoing leading to the damage. Like neglecting usual engineering practices, or even knowingly selling a defective product.
