The 99% of the customers that are notified of the price of the piece, drop the idea of repairing it as is cheaper to have a new one. The funny part is that some customers still decides to repair them, and if you try to call the manufacturer to order the repair piece, either they delay months the shipment, or they end up sending the full original product from some old stock as replacement to give to the customer (or to disassemble in the repair shop if the customer still wants his one).
If current laws are, how to say this, "creatively (but legally) avoided" by companies, I really doubt that new regulations will help at all.
