I never bothered to check, but are there multiple organizations making different names? Or just one that has no consistency whatsoever

They name by committee. So every corporation that is in the USB standards group will argue for whatever benefits them, with no consideration for consumers.

I fucking hate it. Buy a USB C cable and it's a crapshoot whether it's USB 2 with no power delivery, or poor quality with power delivery. Just trying to find a good quality USB 3 cable is difficult, with 3.1 or 3.2, x2 or not, shitty control chips, etc etc.

It is absolutely infuriating. It blows my mind that you can have a USB 3.2 Gen2 cable that does everything you need it to, except for the fact that it doesn’t support Power Delivery and a lot of the time you won’t even know, so if you’re sending high wattage through it there’s a real possibility you’re gonna burn some to kind up.

In theory, compliant devices can detect the voltage drop over shitty cables and request a lower charging rate.

Anything over 3A or 60W requires the cable to have an e-marker. A little chip inside one of the connectors that indicates what the cable is capable of. No USB certified device should try to pull 60W or more through a cable without e-marker or anything above what the cable can handle if it does have a marker.
