Pre-Fortnite-sage I wouldn’t have been so sure, but they had 116m users at that point and were still banned. Obviously that’s still an order of magnitude smaller, but…
Also Fortnite is not utility application it lot easier to ban a game.
It is much harder for say Google Maps, while we can discuss the "utility" of the Facebook app, even with facebook main, plenty of people use it as critical communication tool.
