As mentioned, MSM (left or right leaning) are vastly different from the most popular conservative news sources for several reasons. Fox is the ratings giant. They could certainly be classified as MSM, though they prefer to pretend they are not. However, they are a massive disinformation source. You don't see the NYT or CNN lie about things like Dominion of Smartmatic, and saying they helped steal an election....especially when they new there was no evidence of it. The NYT or CNN does not turn a blind eye to negative stories about the left, Biden or Harris. We constantly see Fox either ignoring harmful stories about Trump, downplaying them or providing spin.
That list also doesn't take into account things like the podcast/YouTube channels, where the most popular ones are firmly right-wing. Things like Joe Rogan, Charlie Kirk, Candace Owens, Ben Shapiro, Jordan Peterson, Dan Bogonio....they are not know for their factual discussions. And of course there are a ton of popular "influencers" that parrot these right-wing talking points.
And finally, as I mentioned, the right has dragged left media farther right, where what was once centre is now considered left.
So, while it might appear that there are more slightly left MSM outlets, the audience they reach seems to pale in comparison to the right-wing echo chamber that is perfectly fine of not covering negative stories that harm their political goals. Fuck, even MSNBC slammed Biden after the June debate. You rarely see Fox or NewsMax or even the NY Post do that about Trump.
