You need to keep in mind that the new restrictions don't affect most Holos. Look at Pekora's streams, or Fubuki's, Ayame's, or Mio's for example - they are virtually the same as they were a year ago even before (but this time, with more permissions, publicity, and fans). Some of them even made it to national TV now. Noel can still tease viewers with her tits. Marine can still go "I'm hornyyy" with her viewers. Nene just talked to Lamy about shaving her pubes last week. The thing is that, those restrictions aren't so limiting that they would affect everyone, just those whose niche rely on the... yabe side on the spectrum (for the lack of better term). In particular, only two Holos (Coco with her Western's branch of humor and frequent vulgarity and Haachama's virtually schizo arc between her two personalities). I love Coco, but it's true that not every girls are affected in the same way - most aren't.
Coco said it in her member-only stream a few months ago (I don't know if it was related to her decision to graduate) when Cover took Haachama's Haachama series down for review (lasted ~2 weeks IIRC): that Youtube was cracking down on VTubers, and people have been reporting Hololive's channels to get them banned. Thus, the management had to be more careful - Coco said she didn't like it, but understood and accepted that as the inevitable result of getting big.
They have always been serious at idol stuff. The "lol, not idol" was the tongue in cheek joke. This is why I hate the over usage of Yagoo's dream meme - that made Western viewers truly thought they weren't idols. No, they are and have been, through and through. A lot of Western viewers just have a really skewed views of idols and what they can, or can't do (for example: "purity" isn't actually a thing for model idols anymore. There are literally idol groups made of JAV actresses).
Frankly, most people (fans and talents included) wouldn't see anything different. If there were so many people that into edgier content, Coco and Haachama would have much better live viewership. Yet, Coco had around ~2k-5k viewers in a normal stream (no collab or big event) with the sole exception of weekly meme review before her graduation announcement. On the other hand, Pekora, whose contents are a lot more family friendly (with some dark jokes here and there), gets between around 30k-50k almost everyday. It's true that we will need to wait and see, but frankly, I doubt majority of viewers are affected.
