Disagree, this lawsuit strongly supports Epic the component suppliers business as well, because one of those components they can supply and make significant money off of is payment processing.
There is a bit of a conflict between Epic the component supplier and Joe the game developer's goals here, because Joe the game developer doesn't really care whether it's Apple or Epic taking the payment processing cut. Joe doesn't necessarily lose either because Joe seems some benefit (just less) too due to competition lowering the cost of payment processing. It's just not clear cut.
In reality it probably the case that some game developers will win thanks to lower cost of payment processing dominating their cost benefit analysis, and others will lose thanks to worse unreal engine platform support dominating their cost benefit analysis.
