CNN is a little touchy about it:

As always, there's at least two sides to everything:
1. A journalist credibility tracking system wouldn't be a bad idea. People have made websites for tracking presidential promises vs. execution of said promises, and they actually exist for media websites as a whole, such as this one:
http://www.politifact.com/punditfact/tv/cnn/
Now, that webpage hasn't been updated since last year, but it shows that, at the time, the majority of CNN's statements aren't 100% factually true; that most - 37% - of what they say on air is "mostly true". So yes, citizens have a right to question the authenticity & truthfulness of a journalist & tracking those data points over time would be an effective way to see the credibility of an individual media representative. However, like this Verge article points out, crowdsourcing that probably isn't the best way to get to the truth:

On the other hand, Musk has been burned by the media time after time. Top Gear pretended they ran out of battery:

Then a New York Times reporter did the same thing, except the data showed otherwise:

Those were both very damaging media pieces to a fledgling car company, which is especially frustrating because (1) EV's can reduce gasoline & diesel pollution (although they create waste in other ways), and (2) both of those media pieces straight-up lied about it, which calls the credibility of the reports directly into question. The bottom line is that they had an agenda to fulfill & sold the public a lie, so it's no wonder that Musk is angry at the media, because a lot of consumer purchases are driven by media influence. And Musk has car data on his side, which he's been very careful to use to defend every newsworthy Tesla crash with on their official blog over the years.
2. On the flip side, Musk just shot himself in the foot. He's been the media darling for the past decade. He's the new Steve Jobs, minus the reputation of being an angry dictator closed doors, at least as far as anyone knows. He's providing a lot of good American jobs & making good products (lowering the price of safety-focused electric cars, selling solar panels, making rockets), he's endeared himself to consumers by answering their questions on Twitter, and overall projects such a fun image of the company that a lot of people are willing to forgive the constantly missed deadlines & buy into the hype machine because they do actually (eventually) deliver. If he's smart, he'll let go of the attack on the media & just keep letting his data do the talking. It's not too hard to get ousted from your own company these days, either...
