Well, they're (a) further up the supply chain that we are, and (b) have the resources to understand and influence their supply chain. You can be pedantic about the word "direct" if you like but I don't think that's useful.
But why draw the line there? If we are making the whole chain liable then why not make the phone case manufacturers and app development shops liable too? They are only one hop down the chain and have the resources too.
