There will be appeal after appeal until the US Supreme Court rules on some obscure fact. My guess is that a conservative court will side with Google. Google might have to change something but it will be minor.
The definition of a monopoly is legally different than what most people think so a jury will get it wrong. To prove a monopoly it must be proved that the customer was harmed. In the app store, Epic is not the customer so they will eventually lose if you follow past case law.
I side with the Jury but a lot of case history has to change for the jury verdict to stand.
