I would say, with respect to copyright, and perhaps I misunderstand the question, but the nature of the way things are shared on Facebook is people. Publishers themselves put articles on Facebook. They put articles, unless it's an instant article.... The traditional way has been to provide a link directly to their web page. In that instance, people, Canadians, would consume the content directly on the page itself, on the publisher's news site.
