Yep, I had the exact same reaction. I don't want any part in this class action nonsense. I owned at least two of these devices, probably three and was very happy with them all. Then again I am an electronics engineer with good appreciation of the laws of physics and not some lawyer looking for a cash grab or journalist looking for a story to hype up.So how do we opt out of this? I knew full well at the time that batteries degrade and with them devices will degrade in performance.
I'm sure there will be plenty of folk who are happy to take "free money" without asking too many question as to where that money actually comes from. Hint: It either inflates future product prices or reduces future innovation.
It's the same mentality that drives people to inflate insurance claims and I want no part of it. In fact my ethics were tested a couple of years ago when I was hit from behind by another car and my insurance must have asked me a dozen times if I wanted to claim for any kind of injury. They were almost putting words in my mouth as to what type of injury would be expected from such an accident. "everyone does it..." - well I didn't.
Anyway, if anyone feels aggrieved by Apple preserving device stability in return for a small reduction in maximum performance then feel free to support this case but for anyone who just wants "free money" when they were not injured in any way then consider how that affects society first.
