Nintendo unnecessarily chose to make their device partially USB-C incompatible in an intransparent way. A lot of users will rely on this working (as it already did on the Switch 1) and then it just won't, and probably the user will just assume their third-party USB dongle is broken and maybe buy another one, which means Nintendo won't get anything out of it and the user will lose more money. Everyone loses but at least the pesky customer can't use a third-party product.
