This may make cheap third-party cables difficult or expensive to produce:

IIRC newer-gen video cables for the iPod did the same thing.

Didn't stop China from making copycats and selling them for $3 on eBay, though...
Sell or send me your vintage Mac things if you don't want them.

AFAIK, those chips aren't for "authentication", but rather, for identification.

The device needs to know what the cable is capable of before dynamically assigning functionality to different pins.
