Eh, you’re assigning an awful lot of malice with no real reason. A smartphone manufacturer already has access to the kind of data exposed in this attack, regardless of whether the headphones were hooked up with wires or bluetooth.
Samsung, Apple, Xaomi, Huwaei or whoever else doesn’t need some stupid BT vulnerability to know what attached devices like headphone are up too. They already have root level access to the phones hardware.
Australia got the criminals while America got the prudes.
