Fortnite seems to have been removed from the Play Store as well
Good.  The sooner a big well-funded company hits this duopoly wall, the better.  They will have the resources to fight this, and the outcome will hopefully be positive for all other developers.Apple and Google are gatekeepers to all mobile devices (practically), but the value they add as gatekeepers is questionable.  Certainly there is some value in their delivery (and much lesser so, their security) service; but their fees are not market set (since they are effectively monopolies by device type).  If there were actual competitors, their rates would be much lower... around 2-5% probably.
