EDIT2: Commenters have some valid criticisms of MBFC.
Here's another in my "making friends" series of posts.
Commenters DO NOT have valid criticisms of MBFC. They are universally wrong, have no idea how MBFC works, and are too lazy to look it up. The misinfo ghouls among them are happy to repeat lies over and over until people start to accept them.
Some of these people can be pretty convincing but I urge you to actually fact check their arguments. Most of these people are just parroting bullshit they saw someone else say. The "best" of these are basically artisanal, hand-crafted AI hallucinations: high-confidence, syntactically-correct nonsense. Don't put that glue on your pizza. If someone posts an MBFC link as evidence, click it and read it. Nearly every single time, the link they posted contradicts them and they just haven't read it.
And ask yourself why no one ever posts peer-reviewed research backing up their claims. It's a simple reason: it doesn't exist. Every single piece of academic research on MBFC says they're wrong. The MBFC conspiracy theorists can't just ignore that body of research because it's inconvenient -- they need a compelling reason why all research to date is wrong. For their claims to be true, it would require a massive conspiracy between academics, journalists, and media bias organizations because they are all in consensus about what makes good and bad news organizations. It's loopy, tinfoil hat bullshit.
