Take apples policy.... The more it costs the better it is.... But we all know that's not true!
Obvs with all new technology, initially expensive, to cover design costs, manufacturing costs as quickly as possible.
Then as manufacturing improves, and competitive companies come along, the price lowers.
Take for example lightning/usb-a cables. At first very expensive, so you used the one that came with the phone, exclusively. Then next year, more people make it, and price drops. So you buy different cables for different situations.
At the moment, to create, thin cables to go in a pocket/small bag, but you want that cable to be fast, it costs money (design n make)
I remember when buying MMR cards for a mobile... OUCH for large memory,... Now I can buy 16gb class 10 MMR for under £3 (GBP)
The same WILL be with usb-c stuff n pd... There are cheaper makes out there, who make similar promises, but we know ANKER is the best. To be n maintain the best takes money.
