This ruling is what I expected and seems quite reasonable. Epic doesn't get temporary special privileges to break App Store rules (even though they are alleged to be illegal), but also Apple can't retaliate against them in other areas.
If Epic does reverse the payment changes in an attempt to return Fortnite to the App Store until the lawsuit is resolved, I doubt Apple will let them back in unless forced by the court (despite Tim Cook's "Sir, we do not retaliate or bully people").
There have been many over the last decade and Apple's behaviour has been consistent i.e. they will simply allow Epic to come back onto the store and pretend like nothing ever happened. Exactly like we saw recently with the Hey app.
Apple doesn't want to punish developers but they will play hard ball if they don't abide by the rules.
But it's also the first publish dispute where someone purposely put in code to activate alternative payment options and broke the rules. Apple is setting an example of epic. Don't break the rules.
What Epic did was hide code and later enable the feature.
Basically now it’s the best time for them to do it, Apple is a huge target and they can gain industry support, Fortnite is big enough that even the average judge, jurist and jury member is likely aware of it and right now they stand to lose very little financially from not being on iOS while the potential future gains are insane.

Fortnite brought Epic £1.8b in revenue for 2019, there is no way that 25% of that came from iOS based on actual player data and experience, if their iOS revenue is 10% of the total I will be in shock.
The US is about 80% of Fortnite’s but the majority of the players are on consoles not mobile. The 80% figure will change drastically when China grants epic permission to monetize the game as the vast majority of their players are in China.
IIRC they said 11% during the hearing, I don't remember if that was 11% of Fortnite revenue or total revenue, and I don't remember if that might have included android as well.
Android is likely a much much smaller to the point of being a rounding error for Epic right now, there aren't many devices that can play the game right and in the markets that they actually get revenue from they aren't that popular.
I don't think Epic has any other games on the App Store tbh, and they probably didn't include licensing revenue.
