So I find claims that MAGA (or any other group) has captured the media to be self-contradictory: if they actually had, you would not be writing that, and I would not be able to read it. By definition. Capturing the media means that there is only one official narrative, and the population is completely unaware of anything outside of that narrative. Like the period from ~1950-1995, where you had the big 3 TV networks, and then each city had their own newspaper that basically owned a local monopoly, and they all basically printed/aired the same stories and same viewpoints.

IMHO what we're actually seeing is a huge fragmentation of the 4th estate. There is now a viewpoint on the Internet for everything, no matter how insane. That's part of what people don't like about it. This fragmentation of media has allowed airtime for MAGA views that would've been considered far outside the Overton Window just a decade ago, but that was the point of the Internet. And it's not really to the exclusion of other views, it's just that you have to go looking for the other views.

I find the definition that unless the capture is 100%, it isn't actually capture to be utterly absurd.

Any strong, independent media ecosystem would not be so consistently sane-washing the firehose of crazy that we're being hit with every week, or kowtowing with such regularity.

Yes, you can find some obscure blog that will broadcast literally any cherrypicked viewpoint. That's not the majority of the media consumed in this country. Even when the owners of the networks differ, the message they broadcast is incredibly homogeneous.
