It's generally accepted that a jury verdict is final at the moment it's accepted by the trial court. So no "alleged" is needed. It's not technically wrong to use it as a descriptive choice, since it's now both factually established and still alleged, but it's misleadingly tentative and not required.

It’s alleged until the appeals stop, then it’s the final verdict

It's only alleged until the verdict drops. Whether or not they appeal, they are currently found guilty of the crime, ergo, not "alleged".

The same can be said about any crime though, right? If you're found guilty of murder, they drop the alleged and you're just a murder. If you successfully appeal, then the title is dropped.

Apple is convicted of but alleges otherwise isn't that difficult.
