The most annoying part is that there is actually a perfectly fine standard for labeling USB-C cables.[0] If a cable can transfer 80Gbps of data and 240W of power, it's supposed to simply have "80Gbps / 240W" written right on the connector. Some rare cables actually do this[1], but the vast majority of manufacturers just can't be bothered with it.
