Considering how high the bar of customer harm has been set, it's doubtful anyone will cross it except maybe Amazon.

Of course it's hard to prove consumer harm when there's so much vertical integration from day one. There's no before to compare it to.

Perhaps if Apple is forced to allow sideloading and other stores in Europe then the harms will be more obvious and comparable.

That's precisely the point. In order for Apple to have abused their monopoly, you would need to point to a change in their business model which occurred during the period in which they held nominal monopoly status.

Epic couldn’t point to any new “abusive” behaviour between when Apple was a ~1% market share minnow to when they became a ~50% market share behemoth. This is critical. In order to abuse a monopoly, you need to have abused your monopoly.
