I highly doubt that.
shmerl: You are missing one point. When Aspyr were releasing it on Steam, they negotiated that with Apple. I.e. they listed all stores they planned to release it in. Apple agreed. Now to release it on GOG, Aspyr probably have to re-negotiate with all distributors which includes Apple (at least I suspect they have to, that depends on how the contract was written). And Apple being Apple can just jerk out and say "we don't want any more stores added, get lost'.
Apple never asked us if we plan to release our apps on another platform and this is also not a valid reason to get rejected on the App Store. Granted, we don't do games, but the rules are the same for all categories.
Sometimes, if a developer is part of a big Apple keynote, e.g. during WWDC, they secure some timed-exclusive apps and it also helps you to get stage time if you're using cutting-edge features of the latest iPhone or macOS.
But in general, even the biggest iOS titles like Monument Valley have been ported to Android after some time.
