They are going to go from locking out teams from divisions, to locking out manufacturers, and through them, their teams.
.....or maybe everyone will pay?
Personally I would like to see a wholesale refusal. Send them back to the drawing board to come up with another way of milking the industry and everyone in it. I don't believe its fair for teams that want to play the events to be precluded from them because their sponsor is not able to justify (through ROI) the 30-50g being asked.
The teams will suffer, or will have to change sponsors/loyalties. If the manufacturers didn't pay, they would end up financially better off.
I hope this falls flat on it's face. Its a truly crap idea.
