Does intent matter all that much when seeking damages like this? The damages happened, and Uber admitted to being the cause of the damages. If the law weren't some complex beast (and we know it really is, so this could be false), all Gett would have to do is prove damages, and prove that Uber did it, and that'd be that.
Can Gett actually prove there were any damages at all? Not only was Uber paying cancellation fees, but unless Gett can prove that this caused at least one "real" Gett customer to not be able to book a ride, then it's hard to say that there actually were damages.
