The issue is in the story teller. If the person telling the story doesn't understand what other data they're leaking or the data the people they interact with are leaking you cannot take their word that "Facebook is listening to my microphone" at face value, no matter how frequently they say it.

Also wouldn't a constant stream of audio - even low quality audio - ruin battery life? I realise it's a phone so it's base usage is a constant stream of audio but I can't help but feel that or something else would be giving it away.

As they have a bug bounty program I imagine there's plenty of people watching raw network activity between app and Facebook too.

Facebook is a well-known battery hog, at least on iOS. I can't imagine their devs are any better at Android.
