That judge's ruling was essentially overturned last month on appeal.
> Even though Apple was no longer prohibiting linked-out purchases, the district court held that this new approach effectively prohibited linked-out purchases, and it violated the spirit of the injunction. The district court then enjoined Apple from imposing any commission or fee on linked-out purchases. However, the Ninth Circuit panel found that the complete ban was overbroad and punitive. Apple should be permitted to charge a commission based on costs that are genuinely and reasonably necessary for its coordination of external links and linked-out purchases, but not more.
"Genuinely and reasonably necessary", not being defined, will naturally be taken by Apple's malicious compliance department to mean "26%", I'm sure, and we'll get to enjoy a continued round of show trials in court with no meaningful effect for years to come.
