I remember soldering these cables together. It always seemed crazy to

The underlying problem is that both ends egotistically expect to be

(thanks for your link) gives an idea of the price, and in this case I
can see some justification for it because they describe the
electronics hidden inside the plugs (we hope).
But considering that two NICs cost less than that cable, I'd need a
pressing reason to purchase the cable instead.
