So how about this scenario: someone with a terminal illness has access to the files. Said person sticks their copy in a timed release, so when they die, the documents are distributed everywhere.

At this point, enough people have access to the files that such a thing is feasible.

Of course, it’s also possible that enough of the files are so boring and inconsequential that nobody would see the value in releasing them like that; the main power is to leverage the innuendo to direct public opinion in a timely manner.
