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).
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.
