Based on recent events and observations: Red Letter Media has a pretty large, dedicated fanbase and doesn't pander to special interest groups or whatever, shockingly, you don't need to do that to gain an audience, unlike all of these Web 1.0/2.0 leftovers out there trying to remain relevant.
RLM is a totally independent company that grew its fanbase organically over a long period time and I think, due to this authenticity and, I'll say it, integrity they get a lot of hate from the Usual Suspects, including the Professional Geeks whom they mocked with the Nerd Crew videos. Such as, from The Hard Times, aka "The Onion, but for Video Games and When It's Lame, Even Lamer than The Onion at It's Lamest"

You can never trust "professional geeks," they're all corporate bootlickers - either access media flunkies or clout seekers or both. You see them join in with the RLM haters, the people who hate RLM for bagging on Marvel and Star Wars movies but probably lack the self-awareness that they've got parasocial relationships with these movie franchises, and who pretend Mike and Jay are trolls who "just hate everything," when they actually often champion films they like.
Red Letter Media fans have much a greater self-awareness (and a sense of humor) about their "parasocial" (there's that word again) relationships to Mike and Jay and Rich than the Professional Geeks have awareness of their parasocial/symbiotic relationships to corporate entertainment franchises.
