That's not all of what he did, though. He'd data mine it like crazy, and would get into areas he really shouldn't have been in (Apple Arcade before launch, etc). The fact that this is all Apple did to him (killing his developer account) is pretty amazing.
Based on the kinds of things he showed, I am fairly certain that an employee was providing him some sort of access to an internal carry build, which is entirely outside of the developer program agreement (and possibly into an actual courtroom.)
