I haven't had my coffee yet, but I'm having trouble understanding your claims (about Google Drive deleting TVEC content) and how they relate to the OECD document you linked. That document does not state that Google (except YouTube) is a member of GIFCT. Further, on page 124 (in "Policies") of the document it states that Google Drive will prevent sharing of files it finds violating, or maybe ban an entire account in some situations.
Am I missing something here?
