Actually, Ron Dennis apparently wasn't even aware of Coughlin's contact with Stepney over any Ferrari technical plans, although it's not been proven as a fact. A number of people in those circles have vouched for Dennis' integrity on that subject though.

The dossier was found at Mike Coughlin's residence during a court appointed search of the house following the British high court investigation of possible interception of classified technical information belonging to Ferrari. If Ron Dennis even had prior knowledge of Stepney talking to Coughlin. he likely didn't think anything of their contact at all, since both the men were friends since working together at Benneton some time ago.
