Plus Epic does not really proposes the same kind of walls as Apple do. The worst they can do are exclusive titles on some typically somehow open platforms (and yep I guess they would take a deal to have an authorized store on a closed one, but for now I'm not sure such beasts exist anyway -- and again, why would it be worse than a monopoly?), they don't even sell only that, and the people they get exclusivity from had the choice to do something else anyway (without renouncing to whole platforms)
