I know TB3 is not USB-C, but as long as a TB3 cable is USB-C compatible (can you really call it "backward" compatible if TB3 is not USB?), that cable is a USB-C cable. You can use it to connect 2 USB-C devices. That means there is more than 6 kinds of cables you can use to connect USB-C devices to each other, contrary to what the article says.
