Does anyone else realise how silly those 2 Spaniards look by getting into trouble over e-mail? At least James Hunt, Keke Rosberg and even Kimi did it glamorously with lots of women and alcohol.
Anyway, the information that was apparently obtained has limited use. Aerodynamic solutions will still need to be adapted for their own chassis, but the telemetry gives an insight into the tyre and pit strategies that might be used.
McLaren's cars rode the kerbs better than Ferrari's in Monaco, Montréal and Monza, so we can be certain that it isn't something that was ripped off.
