You're all tripping balls if you think any country aside from Japan influences decisions made in 90+% anime (or more importantly, manga and light novels as that's what most anime adapt from as opposed to being original) and even that's probably a conservative estimate.
For fucks sake, in an interview with the director of Darling in the Franxxx, when the fanbase outside of Japan was brought up, the director said, "wait, we have fans overseas?!"
Like, yes, due to social media, there's been a bit more interaction between international fans and anime staff, but there's little to no evidence it makes creative differences. Anime is the same as its always been with a wide variety of genres and tones. Anyone who actually follows the medium to this day can tell this.
