Except Epic's theory of the case is not that Apple has a monopoly over smartphones, rather they have a monopoly over distribution of apps on iOS devices. Which would have been true back in 2008 or 2009 as well. If Epic wins their case based on the reasoning they have presented to the court, the same reasoning will apply to all "walled garden" hardware.
It's important to keep in mind that this was merely a preliminary hearing, not the full trial. It was abbreviated by design. The entire thing was a couple hours at most? The only question at issue here was temporary injunctions. Nobody had time to present their full trial arguments.
Sure, the hearing yesterday was about the preliminary injunction. But Epic's arguments have been made in detail in their extensive filings with the court.
