Some employees, especially if they're volunteers and not bound by any contract, might be irreplaceable. The web domain and the server hosting might be in Bob's name (because ten years ago that was so much easier to set up), and he's under no obligation to turn over access information. If you really piss him off, he might just delete the whole caboodle. Even if he just drops out and doesn't answer you calls and emails, you're now pulling all documents one by one for the server and start over, and hope that the hosting company lets you take over the domain when Bob's payment runs out and he doesn't renew.
If you now add that the submitter is clearly not up to date on how to run a large document system (Google doc's, really?) the potential for stepping on toes and causing huge damage to the organization is there.
