Then they’re not standards compliant and they can’t claim to have usb-c on their phones. I wonder how that will work out for them?

USB-C is the physical form. Does it actually dictate USB3?

No. Type C is just a shape. Pixels have had 2.0 transfer speeds too. This really isn’t anything out of the ordinary. It doesn’t NEED more than that honestly. We’re not transferring massive music libraries to our mobile devices any more.

This is absolutely wrong. The spec mandates that USB-C ports provides at least USB 3.1 support. Also USB-C is mandated for USB 3.1.

So to be compliant every USB-C port must support USB 3.1 at least. And you cannot support USB 3.1 with anything other than a USB-C port.
