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.

Yes I think you can just save the readonly doc to a new writeable doc anyway.
If that is true, what is the point of this password remover?
Sometimes document provenance matters and you don't want a copy.
Hmm. I don't really get that. If document provenance matters, don't you want to keep it read only?
Or append-only (think Git)
