I personally have no opinion about CNBC and their relationship with Tesla. I'm only pointing out that it isn't fallacious to account for possible biases if they do exist. It's not just subjective assessments either; take a look at the short interest on TSLA, and the pricing of the put options around their reporting periods; they have people putting down a lot of money on their anti-TSLA bias, and have from what I've seen, quite frequently taken a bath as a result. (Now, there are reasons to believe that they are overvalued, but that's true of a lot of stocks. TSLA in particular seems to pick up a lot of this sort of behavior way beyond what the performance to date has justified. I can't speak to the future with total confidence, of course, or I'd be getting rich.)

I wouldn't be surprised if they have an anti-Tesla bias, though; while I don't know if CNBC has it, I have observed such a thing definitely exists, at a level above the baseline that any company would be expected to attract. But it seems decently balanced by the above-the-baseline pro-Tesla bias that also exists, so, shrug I guess.
