Haven't Apple heard of eBay?
Indeed, there are also concerns that if the rules are introduced too quickly it could mean that perfectly good tech with plenty of shelf life gets dumped prematurely.
If your charger breaks, and it is the only one you had with an old style connector, there are thousands advertised on eBay every day. If your device breaks, who can resist buying a new one. Especially since you will already have a USB-A charger or 3 in a drawer and a USB-A to USB-C cable.
The only thing that stifles innovation is Apple with their attempts to maintain a walled garden and forcing their customers to update all their gear because the new stuff doesn't have at least 1 previous style of port.
