I think the problem is with how close you're getting to stranger's assholes if you can tell from smell how they clean them (and I say this as someone with severe sensory processing disorder who can smell everything - I have never, ever smelt anyone and thought "that's shit, they must not have a bidet". Ever. The fact you have is significantly more gross than the ass cleaning habits of strangers).
Imagine caring about how anyone else (aside for your intimate partner and/or possibly someone you care for) cleans their own asshole.. 🤯
It's hard not to care when you can smell them, but tbf that says more about the individual and not what toilet attachments they may or may not use.
