Point isn’t whether it’s right or not. The point is that once the supreme court rules, there’s no “higher” court to take it to. The lower courts can’t rule differently on something explicitly ruled on already, and they can’t “overrule” the supreme court since they are explicitly “under” them. So regardless of what Starlink says, they aren’t going to change that, at least not any time soon. And X will either be dead, irrelevant, or significantly modified by the time the court changes enough to get them to change their decision.
