Fair enough, but in every instance in my professional experience where presentation data has leaked (unauthorized) - or full presentations themselves - they were sourced/obtained/provided by a former internal employee of the prior firm, or a current employee with strong enough ties to the recipient to justify the procedure.
Granted I'm somewhat biased in that a lot of the work experience I did in presentations was for public entities who had significant channels for obtaining submitted documents by all interested parties (e.g. Florida's Sunshine Law). Even with marking certain things "Proprietary and Confidential" there were judgment calls to be made about what to put in and why.
Yes, on several occasions the submitted materials ended up being used by the potential client and their current service provider (i.e. investment strategies), and with little to no recourse. Cost of doing business. Can only protect so much.
