Reading through it quickly, it looks like this is for files that are available to read, but write-protected? Not read-protected documents like a password protected Excel workbook?
A modern read-protected Office document is AES encrypted, so you cannot read those at all. But the read-only one, much like PDF do-not-print/do-not-copy protections, is just relying on the viewer to honor the protection marker.
