I've been getting off of YouTube more because now creators censor themselves even more than network TV does.

You can't say "kill", you have to say "unalive" or "took their life" or shit like that. You can't say "rape", you have to say "SA". You can't say "porn", everyone called it "corn". Apparently you can't even say 16, because I saw a YouTuber say "61 backwards" when talking about a creep on the internet. I remember one YouTuber censored "damn". It's one thing when it's like a comedy video, but what bothers is when you have "true crime" YouTubers who end up censoring half the video because it turns out that you really can't talk about murder without saying the word "murder", or "killed", and in the case of serial killers "rape".

I can watch Law and Order: SVU that uses all those words, and that was on network TV, the one where the FCC could actively block bad stuff.

So at this point, YouTube has become a pretty sanitized place filled with sanitized content, even more sanitized than network TV, which is fine, but it's sort of the opposite of what I liked about it from the get-go, and it has gradually become less appealing to me. I understand why these creators are afraid to use the actual words (advertisers and the like), but I have found a lot of content to be pretty bland as a result.

Part of why I got into YouTube as a teenager and onward was specifically because creators were allowed to act candidly. They would say curse words and talk about things that interested them. It was cool.

the fact that I'm into a lot of the topics that you've listed but have never heard of these creators simply underscores the sheer scale of youtube

This just highlights how YouTube is a different thing for all users. One person's experience can be radically different from another's. I wouldn't even know someone like MrBeast exists if Hacker News hadn't told me about it. Most of what I watch on YouTube is regular media that would otherwise only be available on obsure local networks or DVDs that I don't have, like Thrasher's skateboarding videos, broadcasts of the X-Games and Red Bull action sports events, ESPN/CBS/NBC highlights of yesterday's major pro sports events I didn't watch because they're on too late for me, or music videos via YouTube music. None of these are YouTube "creators." They're just normal media that uses YouTube as an additional distribution channel.

Honestly, my favorite channel is probably BBC to watch snippets of classic BBC Earth series narrated by David Attenborough. I'm pretty sure I could get them through HBO Max, which I believe is the US streaming that has distribution rights for BBC Earth, but it's convenient to get stuff like this all from one place and pretty much everything has a YouTube channel.

I watch more YouTube anything else combined by a pretty significant margin. I'm sure there's a lot of crap, but it doesn't show me too much of it. It has learned my preferences well enough to know that it should show me chess, Mario Maker, Australian machine shops specializing in resource extraction industries (a very specific genre to be sure, but I'm subscribed to two separate channels here) and various other things of that nature.

Things don't sound completely rosy for creators who want to actually make money from it, but it does seem like they manage to get by. From the perspective of a viewer, they absolutely deserve this.
