Not a final decision. SCOTUS (via Kagan) refused to overturn a stay on a decision while legal proceedings continue. Basically just an order to keep things as-is until the case finishes working its way through the courts.
Which as I understand it is generally how things work: if there’s no clear likely winner, go with the interim situation that most easily can be rectified if it is later ruled to have been wrong. In this case, if the ruling goes against Apple than they can be ordered to give money to Epic and other app-owners based on the revenue brought in from them to Apple during the appropriate period. The opposite case would require more complex estimates (how much revenue was shifted away from Apple incorrectly, in the case where Apple wins) and further it’d result in unnecessary consumer friction: users would go from A to B then back to A again.
This is a result of a SCOTUS decision. SCOTUS membership is determined by the president and control of the senate at the time of vacancies. Neither of those are influenced by gerrymandering.
At the core of it this comes down to 2016 when a larger than typical number of people on the left lied to themselves and said “eh, they’re all teh same” and tossed their vote at a third party or just didn’t vote at all. Following that, SCOTUS went from a 4-4 tie (with 1 vacancy) to 6-3 conservative advantange.
I wouldn’t blame laziness, but instead a combination of apathy and people who are more interested in ideological purity than in accepting the available-better such that they would rather complain about the unavailable-best.
RBG refusing to retire in 2012-2014 also shares blame. She could have retired then and the court would be 5-4 instead.
