realistically, CG nor EA care at all about players leaving the game. They expect it, even if the top whales are leaving because they already made a nice chunk of money off them.
That is even more true now with all the catch up options they're adding to the game now so they can get new players to build up faster. It would be great to know what their actual priorities are, but they aren't allowed to communicate that kind of thing with us. Only the bare minimum of information about the next upcoming event they want us to spend money, time, and resources on.
If the top 10% of spenders in this game all quit, they might tell whoever is in charge about that. But the response will be, "really? Hmm, I wonder what that's about. Hey, if you're going to get coffee, can you get me one too?"
