Wasn't TB supposed to be an open(-ish) standard, meaning no licensing fees?
I think they should have learned from the meh performance of firewire (which required licensing to implement) versus the free USB, which became the dominant format.
Also, the continuing move away from proprietary DVI/HDMI in the computer space to the free and open Displayport standard shows you will have a hard time gaining any traction if you demand fees from manufacturers.
