There were those who were sounding the alarm about this lab leak hypothesis well over a year ago. The overwhelming media narrative to look away from that hypothesis and smear those who talked about it was always artificially manufactured in a way that should have been obvious to most people.
But this kind of misinformation is really par for the course with the mainstream media. If you're only paying attention to ABC, NBC, MSNBC, CNN, NYT, WaPo, etc. (and downstream from those sources) for your day-to-day news - you're in the worst manufactured media bubble in existence. Those big media companies are a locus of power that is manipulated to an incredible degree.
I'm not telling you to drink the koolaid and only watch Fox News while reading Breitbart. I'm definitely not telling you to waste your time on Alex Jones or someone like that. I'm saying to balance what you look at with other information sources with a variety of political slants. This WIV narrative is just one of many that the MSM has been pushing over the last few years. It scares me how gullible people have been on so many topics.
There's this general situation where yes, there is that ecosystem 1 and downstream sources OP mentioned, and there is the ecosystem 2 (Fox and downstream sources).
However, former POTUS and ecosystem 1 cycled between themselves a fair bit, ecosystem 2 and former POTUS cycle, so by proxy eco1 and eco2 are cross-linking to each other in a sense, and so on.
I'm not telling you that there is no good way to parse info sources out there, but I am telling you the "MSM vs. other" delineation that OP is calling for awareness of doesn't really exist if you study the actual information flow... which this team did.
If you want my advice, read primary sources on events that matter to you. Studies, court documents, and so on. It's what that whole confusing ecosystem uses as well, and you can get the raw data without the analysis.
