I'm not sure I buy the vendor lock-in thing, if that was the core motivation why not at least bother to use a custom USB-C connector? This way you wouldn't have to deal with the reports of users plugging other USB-C peripherals and getting crashes. Seems more likely what whoever implemented that part of the Switch did a poor job. Was it even done in-house or did they contract a 3rd party to hack it?
