Yes, but I'm pointing out how the cable is part of it in ways that wasn't true for many older standards. So if I plug a non-data cable into a data USB-c port (say a digital camera with AAA / LR6 batteries) into a computers USB-C port then nothing happens. Same if I try to charge the camera by plugging it into a USB-c wall plug. Or if try to plug my phone into the USB-c charging port on my laptop, no matter the cable since neither phone nor laptop has the function to charge other devices. Etc etc.
I work IT and while I don't work directly in support anymore I still get people at the office coming to me for support because I used to and we've outsourced it now. So I know first hand how confusing USB-C is to average users.
Even if you use a data cable, it might not have the pins/wires for usb 1.1 fallback meaning a keyboard or mouse won’t work with it. Or it might support low power only. I had to buy a usbc cable tester to validate which ones might actually work with what.
My favorite is that not all chargers support all voltages. I have a few that do 5v, 9v, and 20v, but if your device asks for 12v, you’re out of luck, you either don’t get anything, or it fails back to 9v which isn’t enough to accomplish what the device wants to do (like charge). Still, it’s standards compliant!
The standard explicitly allows but doesn’t require support of any subset of standards so you never REALLY know what that cable or charger in your hand or the devices you’re holding can actually do without finding specs in docs… It’s really infuriating. The idea of USB-C is better than the reality, which makes the push to standardize on the connector not nearly as cool as it could be.
I have a portable switch dock (it's the size of a small power brick) and the cable that came with it broke. Finding a cable that supports the exact spec that the Switch needs to both get enough power to put it into docked mode and transmit the video signal took a few tries.
