Yeah that must be the real reason it didn’t catch on as a default. Light peak did have cheaper cables though, the optical part was in the connector, not the cable. The connector was a usb-a connector if I remember correctly.. and the history is actually pretty interesting! Apparently that connector was deemed proprietary and frowned upon by the usb folks for causing consumer confusion[1]. Kind of hilarious now, seeing how thunderbolt 1/2 ended up barely being adopted outside of Apple and usb itself is a confusing mess these days.
