I am reasonably certain (let's say 90%) - that Toshiba put some effort into deciding that their policy, as a whole, would be to shut down third-party distribution of their service manuals. This is not the case of an overly enthusiastic legal department. This is their company policy. Suggesting otherwise is giving them credit where it is not due.
