Along with the desktop store, it's like epic and Tim specifically try to do as little as they can and then get mad at the lack of user adoption. I hope O3DE and Godot keep developing and gain in adoption to topple unreal engine and more games come out and eat away at Fortnite. If their cash cows went into decline maybe they'd start doing more than what they think people should accept as the minimal viable product to spend their money on

Epic winning this case might just open that for them.

On the other hand, do they want to enter the mobile market? They're a privately owned company, so they don't have the same shirt sighted pressures to chase exponential growth endlessly, like cancer. They are already making money hand over fist.
