I'm very confident the old Steve Jobs emails from the eBooks anti-trust case will also be brought into the trial to argue anti-trust is in Apple's DNA.
That's also the reason for that silly 1984 ad parody, so they can bring Apple's original 1984 ad into the trial and make an argument of hypocrisy in front of the Jury - once they were plucky upstarts but now as the most valuable company, they're vampire like etc.
Other vendors are also at this same time taking the opportunity to test Apple store rules limitations - either for Epic to be able to add those additional arguments to their own case OR possibly for them to get standing to join the suit - look at the PR yesterday around Facebook donations to creators hurt by Covid being blocked by Apple store rules.
In this situation, there's very little role the judiciary can play except move the process along. It's going to be a fun battle to watch.
