Except they’re being new and without market share is exactly why they’re cheaper. Epic isn’t running an altruistic enterprise here.
It was telling that after circumventing Apple’s 30%, they didn’t offer their goods 30% cheaper - or even 18% cheaper (reflective of the 12% they think is “fair” in their own store), they made it 10% cheaper for the user, and kept 8% more for themselves than other developers on their own Epic platform would get.
Absolutely the App Store does a lot of discovery - just ask anyone what being a featured app does.
I find plenty of apps by searching.
Anyone whiteknighting for epic here is going to be disappointed in 5 years when they’re either successful with their store and raking other devs over the coals or they’ve shut their store down completely.
