This does seems like an abusive move by Apple. I note that Epic continues to provide a version of Fortnite that violates the rules and provides the ability to buy in-game currency at a lower price through their own store, and has filed legal papers requesting that Apple be forced to support this while the court case proceeds. This seems like an abusive move by Epic. Two wrong don't make a right, but it's tough to see how this isn't a direct result of Epic's actions, and more to the point, something Epic could fix in less than an hour by turning off their violating store. Turn it back when/if you win the court case, Epic. Right now it seems like you bet that Apple wouldn't call your bluff, and you lost. They did.
