Bought mine from China for cheap. They work like a charm. Been using them for the last month on 6P and 5X no issue whatsoever. I wouldn't get caught up in the mythology.
There's no "mythology" ... either your cable has the correct pullup resistor, or it doesn't.
And yes, all cables will "work," you just won't know there is any problem until your charger/USB-port/motherboard/etc., dies.
