Many people on HN seem to think that it's perfectly OK for Nintendo or Sony to charge a 30% platform fee for Fortnite but somehow not OK for Apple (or Google) to charge a 30% platform fee for Fortnite.

Epic wants to force Apple to lower its platform fees so that it can pay lower fees to Apple for Fortnite (technically IAP since Fortnite is "free to play") than what it pays to Sony and Nintendo (or Google for that matter) for Fortnite.
