I don't understand your point. When you send your data to Google or Facebook by explicitly providing that data, you are giving them permission to use that data for purposes of providing the service for which the data is granted. This is true everywhere, even in the EU. If you're asking whether that upload would grant Googlebook broader rights to use your data, then the answer is yes in the US because there are no laws currently restricting such use, but no in Europe because EU law says permission must be explicitly granted for other uses.
