If you were to look at the impact from corporate misbehaviour/corruption, then in my opinion it's pretty clear that there's a war, and that the journalists are going to lose for many reasons. For example the VW emissions cheating scandal, they took a "big hit", but it's been mainly forgotten and out of the news, very carefully "damage controlled" - no doubt also using social media. There's no real political will (and political protection of economic interests), there seems to be an acceptance that "they all do it" (cheat and tell lies), so "get over it - move on".
I don't expect much more will come of Facebook's treachery, sure they have taken a hit (share price) but whether that cost is greater than the past increase in share price based on profit projections from mis-using mined data is moot. I don't expect there'll be a hell of a lot of political will by any who'd used CA (or others) to change or regulate.
Slowly, freedom is being eroded under the implication that "regulation hinders business, business is good for people, regulation is therefore bad".
