All this because Apple has build this idea that the more closed their ecosystem is, the better it is for YOU the user and themselves.
Epic got the David vs Goliath syndrome and used fortnite users ( teenagers ) to "fight" against Apple status quo
Meanwhile we see Microsoft joining the battle because of Microsoft recent strategy ( put your services everywhere) will only work if Apple ecosystem is open.
Let's s not not fool ourselves, this isn't about us users/gamers at all. it's just big corporations trying to take a bigger slice, maintains their status and change things for their best interest.
None of those corporations has morals.
