Show me a GPLv3 draft that did it?

Start here, section 3:

Doh.  Then chmod og-r is DRM too.  And stronger DRM while at that,
since the user denied permission to read the file cannot take it back,
whereas the verification of unsigned software is just a warning, that
you can often bypass by telling the software to go ahead and install
it regardless of signatures.
