I imagine Epic doesn't really care about that so much as not giving Google 30% of in-game purchases in Fortnite.

Google isn't being forced to do anything. The judge specifically stated they're not doing injunctions or anything. If Epic has another problem, "you can come back."

Now, that's still a ruling, and a ruling helps dissuade Google from doing certain things, but there's not likely to be anything "forced" here.

If Epic aren’t suing for damages I don’t really see what the goal could be

As reported by The Verge,

Epic says it’s asking for three things: freedom for Epic and other developers to introduce their own stores without restriction, total freedom to use its own billing system, and an anti-circumvention provision “just to be sure Google can’t reintroduce the same problems through some alternative creative solution.”

Judge Donato says the last won’t happen: “We don’t do don’t- break-the-law injunctions... if you have a problem, you can come back.”
