You compare a company ( Apple) who invested billions of dollars in ecosystem, hardware etc. In dev tools. It's not even fair to compare it with parasitic company Epic. That is leveraging platform been developed and pretty much created a market to leverage human weaknesses ( gaming). They don't bring any real in this world. And yet they dare to say they not happy with market that brought them billions. Such kind of ideas can only appear in such kind of company, that don't bring any value to the world and thinks that the world owns them something. Huge part of Epic success is apple marketplace that users trust. Even google play is a derivative from Apple's ideas due to Eric copy pasted while been a board member of apple. You got access to billions of people thanks to apple and google, using their tools. I think it's logical apple and google want their cut for that.
