> People who actually tried to use it for a number of things quickly realize that USB-C is just the name of the physical connector, which has nothing to do with what the device supports, which in turn has nothing to do with what the (unlabeled!) cable supports.

This is also true with USB A, B mini-A and mini-B, mini-AB, micro-A and micro-B, and micro-AB; also A, B, and micro-B actually have two versions each of the connectors, with compatibility in one direction, so you don't even always know that physical connectors are compatible from the connector name without also the USB version.
