the standard is pretty clear and give options to make a cheap or expensive product. the shock is that apple and samsung both decide to make very expensive products, that implements the "cheap" options as a way to lock consumers. ...and there is a fool born every second, as the saying goes. did samsung had to omit the ADC in their dongle? no. did apple had to omit the other bus protocols in theirs? no. their price and volume could have literally made the dongles cheaper with all the features. but doing so lock all the fools in for upgrades and prevent brand move.
