I don't think this is a technical problem so much as it is a political one, on two levels: First, that the spec for USB-C was allowed to have so many variations that it's very hard to know what you're going to get if you plug a connector in (is it USB 3.1? 2.0? Does it support power delivery? At what amperage? Is it actually Thunderbolt 3? etc.), and second, that a fair number of just totally out-of-spec—and thus, essentially counterfeit—products are being (or at least have been) sold on Amazon and similar places for some time.
