Here is an analogy:
In a far-east country, four corporate teams soup-up their cars for the Grand Prix car races. The best race car drivers earn a lot of their paycheck from their specific corporate sponsor; contract bonuses are tied to their performances in these races, and the drivers' contract confers these drivers have to race in the car produced by their sponsor. Indeed, it is understood that for a driver to even found practicing in a competitor's car is grounds for termination of their contract.
Then, one year, something unusual happens. One company comes out with radically different race tires, called the 'Wankel-mee-doo's'; subsequently, drivers on that team start winning, and/or consistently placing high in all of the Grand Prix races. The media has a hey-day: "Is it the new tires?" "Are they even legal? "blah, blah, blah..."
Drivers on the other teams are really starting to get concerned, yet their sponsors keep telling them, "Hey, it's not the tires, our cars have tires with better features. They get better gas mileage, and our car's tires are more durable. And we have already done tests to show our tires are just as fast! Maybe you drivers need to step up your game, or we will find other drivers!"
Nonetheless, these drivers keep losing to drivers on the team with the new 'Wankel-mee-doo' tires, even though they used to beat these drivers before the 'Wankel-mee-doo' tires came onto the market.
So I ask you, would it not make sense that those drivers on other teams now losing to drivers in cars with the 'Wankel-mee-doo' tires, would at least find the means, even in a clandestine manner, to try out the new 'Wankel-mee-doo' tires? If indeed, after doing so, they find out for themselves that the 'Wankel-mee-doo' tires may actually be faster, and run smoother....then they come to a juncture in their career...
