apart from the fact that none of it is actually true and merely an internet rumour for those stupid enough to believe everything they read online, even if it was i implore zuckerberg to watch the inside of my pocket and listen to me fart all day.

Do you have any evidence to support your post?
Since I am one of the ones 'stupid' enough to believe the rumours, I would love to see some evidence that the rumours are false.
Just because you are too stupid to understand why some if those functions are able to benefit FB, doesn't mean you should liken others to yourself.
FB gets it's income from marketing and advertising. Listening in on a call you make us useful marketing material.
Just the same as when you Google something you will find the ads you are shown in FB will be related to recent searches.
Google and FB have been doing this for sometime, but their new strategy is getting a bit invasive.
