If Nintendo is shipping something with a USB-like port that isn't standards-compliant, that's way worse than just about any other company in the entire industry has done.
Like my Raspberry Pi?
Sorry, I meant *intentionally* non-standards-compliant.
Other than that- they're not.
I haven't seen any evidence of a compliance problem- but their dock behavior does appear underhanded. They appear to be using some kind of authentication method, but that is perfectly allowed. They complete the necessary parts of the DFP/UFP and PD negotiation. They just seem to be expecting some kind of vendor-specific VDM for "authorization" before they'll enable DP Alt mode, which is again, allowed. But a dick move either way.
Could it just be that they don't support DP Alt mode at all, and that their dock uses DisplayLink instead? Or that they don't implement the split mode where half the bandwidth is for USB and half the bandwidth is for DP, like most docking stations might typically use?
It's way worse than underhanded. It means that your USB-C Switch can't connect via USB-C to any USB-C-equipped television sets, because those by definition won't send Nintendo's nonstandard VDM. If it were even remotely acceptable to play fast and loose with the spec like that, given the history of the MFi program, you can assume that Apple would have done it, yet iPhone hardware supports any generic off-the-shelf USB-C hub, complete with HDMI.
But yeah, since DP is licensed by a different company than USB, the USB branding doesn't cover it.
