What's the penalty for Apple just ignoring this ruling, if any?
Also they earn money from AppStore advertising (which apps out of the millions should the small screen show); so maintaining AppStore should not be a problem.
I don't know about the bad-actors part though.
Why not?
That's a bizarre question.
They'd be in contempt of the court.

The judge could sent Tim Cook or any number of Apple execs to prison.
They can, but it has a high probability of additional adverse consequences.
Which...is obviously true. I mean, it would be nice if people could not commit murder, but they can and do.
Rather than that, they will use legal means such as appealing the ruling. They are a 2T$ company, and they will try their best to use their money to change this decision in their favor.
"Apple must allow the use of third party payment processors" does not mean "Apple cannot enforce any other rules against apps using third party payment processors". If they decide to go on a harassment campaign of petty violations against third party payment using apps or put undue requirements on them, those parties can complain to the courts and likely succeed. If the third party payment provider is stealing credit cards or obviously malicious behavior in some other area, Apple would likely prevail when pointing to that as the reason they banned them.
In addition to whatever penalties are available in law for the act outside of the ruling, they would also face additional consequences for contempt of court. And its generally easier to prove a violation of the order than a violation of the law justifying the order.
>If any part of this Order is violated by any party named herein or any other person, plaintiff may, by motion with notice to the attorneys for defendant, apply for sanctions or other relief that may be appropriate.
The penalty for contempt of court is often incarceration. Note that the order enjoins not just Apple the corporation but also Apple's officers. It would be highly unusual for the CEO of a major corporation to openly and defiantly flout a court order, but if it happens, he can expect to be arrested for contempt.
