On a slightly tangential note, my company has a massive Yammer install (200k+ account) and I always wonder if people can discuss in yammer group about replacing Office by G Suite, without triggering anything. This is kinda paranoid, but I am still astonished that a company can essentially put all its communications, roadmap, and so on on another company platform. Even if you do not compete frontally, at some point, there are some diverging interests. I understand that the risk would be too big to eavesdrop on your customer, you would ruin your reputation and your product, but still, it seems the temptation even by a rogue employee could be strong. This is not a jab at Microsoft, it would not be better if it was another mega corp platform.
