That's kind of right although I somewhat disagree with #2. It's not so much that Facebook is causing people to not visit news organizations websites that's hurting news organizations, but more so that there are so many ways to advertise to consumers now (largely through Facebook & Google) that the news organizations are struggling to get advertisers to pay them top $ to advertise with them like they used to. Basically, even if Facebook had banned news from day 1 of its existence and consumers had never expected to find it on Facebook, the fact that advertising has become cheaper would itself hurt news organizations that relied on advertising revenue.
