They made a decision to try to keep battery life closer to constant at the expense of performance, believing it was a better UX (slow phone > no phone).
I think this was totally defensible, and I also think that the people who claim it's some sort of malicious activity are unhinged. That said, it makes sense to avoid a lawsuit where you'll spend a fortune in legal fees, then roll the dice on the verdict possibly losing _billions_ instead, and definitely earning a lot of ongoing PR along the way. Better to just pay it once, get one more round of dumb "Apple slowed their phones because they're evil hurr durr" commentary out, and then get back to business.
