Unfortunately, Facebook is not owned by Radio-Canada, so there's no public medium like Radio-Canada broadcasting on Facebook, the Internet, or whatever media you use. Therefore, with any source available, when you rely on your Facebook page, you get tons and tons of awkward information. Government cannot regulate laziness. If I don't cross-check my information, as Mr. Scott said, I'm going to read my Facebook and think the world is the way Facebook describes it to me.
It's all a matter of interests. For me, the important thing is to be able to know what interests are behind the information and therefore have the availability to verify this information with other sources and make up my own mind. Would that be the limit of my intervention as a government, and of course the responsibility of any reader?
