Assuming they are in the wrong, what should be the punishment?
I don't know. The problem is, they got the knowledge that can't be just unlearned. If they really were testing the tyres for Canada, they got the unfair advantage over other teams and drivers(remember, Rosberg and Hamilton were the ones doing the testing), having acquired knowledge of the new tyres 4 weeks before other teams. The fair thing to do would be at least to ban Mercs from the next GP.
But then there's the matter of testing in itself, tyres aside. I mean, if testing 1000Km on a development track with Pirelli data is not an advantage, then let every other team do the same for 3 days. Everyone but Mercs.
