"Pressure by pocketbook" is wishful thinking
These companies know perfectly well that their customers don't have the knowledge necessary to make an informed decision on the security of these products, and will only get to hear about any issues if they blow up enough to make it into the mainstream media - neither of which is a big risk to them, so they just don't care.
Consumer buying decisions aren't going to improve this woeful state of affairs, only effective regulation can. And I don't see much sign of politicians having the understanding or will to make that happen, either.
