But we make the up front cost trade-off at the expense of nothing working right. People buy cables or chargers that don't support the right level of charging. Cables work with some monitors but not others. Instead of paying extra for things that just work, we end up paying for impossible-to-distinguish hardware that may or may not work because of some flavor of the spec that doesn't work with the other piece of hardware you're trying to connect it to. A lot of that ends up being instant trash. Genuine, good hardware that is just incompatible is indistinguishable from badly made hardware: to the consumer they both don't work. And so we end up with waste and frustration in the name of saving a few bucks.
