Seems like it's a new communications channel which is ripe to get PR'd into uselessness, just like the company's official channels.
Maybe it can't be, because there has to be some useful channel to tell people that, no, those ships aren't coming in today or that train isn't going to make it on time or so on, but if the company sees a value in presenting the happy face to everyone, it has an incentive to make whatever deals it needs to in order to ensure all public or not-private channels stay on-message. This works out to NDAs and encryption, usually.

Maybe that's impossible at a practical level.
