That's not what this dismissal means. It's basically saying that the SCOTUS is taking no stance, not agreeing with either side.
But really, this is all based in the misunderstanding--widely distributed in the press--over what happened back in CA.
In reality, CA didn't steal user data. Users handed it to them. I was there, and back in those days users were happily handing over information to these third parties.
But that doesn't make for such a sensational story, so as usual, the drive for click-bait lead the investigation.
This is still cleaning up that mess.
