An unforeseen answer. I thought it would be lower
priced to make an usb device one time and several notebook
manufacturers would buy the device for their notebook.
The going for thinner argument sounds relevant.
I thought making proprietary devices would make it more difficult
and expensive for other manufacturers to make the same devices.
Remarkable that it is lower priced for a manufacturer to make
a device by themselves.
