Underhanded? As a response to the incident they have made it so you can explicitly turn it off, sure. But people trust the phone to make a thousand other decisions on a moment-to-moment basis about the tradeoff between CPU and battery, is it reasonable to call it being "underhanded" when singling out a specific one of them retrospectively? Maybe I'm wrong, but I don't think I know a single person who would choose to trade an hour or two's battery for a 5% CPU bump.

Much like the iPhone 4 reception fiasco. Nothing actually changed reception-wise, except they changed the way they calculated and displayed the signal. But people were now seeing _different_ signal profiles than they expected, and apparently Apple decided (eventually) that changing it back and giving everyone a free case was better marketing that continuing to try and persuade people of that.
