In my opinion, once they put a chip on the battery, they can keep competitors out. You will have no choice but to buy more high-priced batteries from them. It's a business strategy. The power management bull... is an excuse to justify their design for the public. They could have put the chip on a battery hub.
No, they could not have put the chip on the hub, you are only thinking of one function the chip performs, there are a lot more, less obvious functions going on. Probably the most important function is not the simple charging control, but monitoring of the charge quantity.
For safe and reliable flight, you need to know the amount of charge placed in the cells during charge, and the amount that has been used during flight. LiPo batteries do not have any simple method to monitor the quantum of charge, so you need an intelligent system to measure the charge current over the period of the charge to arrive at a figure representing charge quantity. Likewise, the same monitoring system watches the amount of discharge from the battery, and estimates the remaining capacity. For the flyer, these functions are vitally important, and cannot be done without computational power in the battery itself.
