I would, though, appreciate the price being lower as the manufacturer does not have to include a charger, saving on cost of charger, packaging and distribution costs.
Not likely since consumers are already paying x so lowering it makes no business sense; better to just enjoy the windfall. It's like when Apple lowered fees to 15% for small developers you didn't see prices drop as a result.
I have drawer full of USB-C Cables that work with some devices but not others, even though the packaging claims the cable is up to spec.
Actually, the probably are, given the flexibility of the usb spec; I suspect USB really means Usually Standard Bus.
Very simple companies should be required to add a voucher to the box that says "Exchange this for a € 20 discount or a charger for your product with a minimum wattage of XX WATT and XX Volt" (to be specified by the manufacturer).
Which negates the whole ewaste solution since most people would get a charger, whether they needed it or not to avoid "losing" money.
