The decision by the investigating body to punish Mclaren as a team, for an individual employees possession of Ferrari documents does not make sense without implying there is 'more than meets the eye'.
On face value, my opinion is that 'if' a Ferrari employee was responsible for the consignment of those documents, that they, as a team, should be punished equally as harshly as the recipient
One very good point I saw raised was 'who' does the $100M fine actually go to, considering the FIA don't seem to be short of a few bob, already ???
