The hub doesn't have a negotiation chip to set the voltage correctly. It is likely presenting as a bus hub. Like if you do $ lsusb on Linux, you'll see the hub and whatever is connected. That hub may be integrated into other chips or it may be stand alone as a peripheral somewhere on the board. It is basically like a digital cable splitter for the bus. It is only concerned with the data. The power is likely just passed through. For USB-C PD, it would need some complex additional circuitry to negotiate, convert voltages and do current limiting. The way the pins can be inverted by flipping the connector makes it logically complicated.

An easier way would be to restore democracy by making the right to digital slavery – ownership and trade of the digital presence of a person for exploitation and manipulation – illegal. That is the profitable and massive political capital driving the machine.
