>The 30% store tax is a high cost in a world where game developers' 70% must cover all the cost of developing, operating, and supporting their games. There's a rationale for this on console where there's enormous investment in hardware, often sold below cost, and marketing campaigns in broad partnership with publishers. But on open platforms, 30% is disproportionate to the cost of the services these stores perform, such as payment processing, download bandwidth, and customer service. We're intimately familiar with these costs from our experience operating Fortnite as a direct-to-customer service on PC and Mac.

And another interesting quote from him
>If you look at it, the stores on the smartphone platforms actually do very little. They’ll put ads up in front of your game. When you search for Fortnite on iOS you’ll often get PUBG or Minecraft ads. Whoever bought that ad in front of us is the top result when searching for Fortnite. It’s just a bad experience. Why not just make the game available direct to users, instead of having the store get between us and our customers and inject all kinds of cruft like that? It’s a general criticism I have of the smartphone platforms right now.
