Note that this is mostly caused by the fact that mobile game developers are courting such a distribution by making "pay-to-win" games where you can pay more to get advantages without limits. While such a structure means that a game developer can earn 10k or more from a single player, it also makes the game worse for those who aren't willing to spend unlimited amounts of money and thus drives some of them away or causes them to decide to not spend any money at all. If this is not desired, the simple solution is to have an "unlimited pass" that gets you access to all current and future IAP/DLC content that gives a game advantage for either a fixed one-time fee or a fixed subscription fee. This is probably not often done because the game developers believe that it would be less profitable overall.
