This is absolutely not a “US under regulation thing”, that makes no sense. What “regulation” would dictate what a connector carries over its cable? That would be compliance with the spec, and the spec is a connector.
USB-C can carry USB 2.0, 3.0, 3.1, 3.2, 4.0, PD, DisplayPort, wattages from 5w to 100w & Thunderbolt 4. No one cable would be required to carry all those or all cables would be $50/ft.
Just because you’ve never encountered a USB-C power only cable doesn’t mean they don’t exist in your country. They’re made by the bucketload in China, and you’ll encounter one soon enough.
Agreed, but not requiring labeling or some sort of method to identify was a real fuckup on their part.
My problem isn’t the existence of different tiers of cable, it’s that there is literally no way to know if the cable you’re using supports something until you try it.
