> For me the first realization is that puting files on Drive is considered publishing.

Putting stuff on Drive isn't publishing in the usual sense, but Drive can be (and often is) used for publishing, just like every file storage service that makes it possible to share a link to access stores files ever has been.

It's not clear if all the issues are with shared rather than merely stored content, but it certainly seems that the primary context of the issues in TFA is shared content.
