What a weird take. If I'm also in the bathroom, I can tune out all the other noises around me because everyone's in there to do the same thing. If I were on the phone with someone, paying close attention to what they're saying, and then I'm treated to a thunderstorm of bowl challenges, I'm going to be annoyed.

Humans pee, fart, and burp. That's perfectly normal. And yet, it's considered basic politeness not to do those things in a freaking business meeting if you can help it.
