Let's see, a lot of people are confusing platform freedom with the creator's obligation, but I get where the frustration comes from.
For years on Twitch we saw the version "repressed" by moderation: costumes like Shampoo with the ultra-short dress, but where the thrill got killed instantly because you could see the seams of the sports shorts she wore to shield herself from bans. Those shorts weren't clothing, they were a shield so they wouldn't shut down her channel.
When Fannova opened, the logical expectation of the people who paid for the subscription was to see exactly that same cosplay, but without Twitch's censorship filter; that is, swapping the safety shorts for a thong or lingerie peeking out during a little dance without breaking the "no nudity" rule. They expected her to use the freedom of the paywall to take off the safety patch.
If she decides to keep the defensive shorts and the same aseptic cleanliness on a paid site, it's normal that people feel like they're watching an expensive Instagram. But the reality is simple: the paywall gave her the freedom to show more if she wants, not the obligation to do it. Yuuki decides how far she stretches the line, and whoever isn't happy with that limit just has to cancel the subscription.
