Because nowadays people seem to think throttling is BAD for power management. It's apparently much more efficient to IDLE as much as possible to save power, and to do that you should be running the processor on as high speed as possible to get whatever work you need to get done finished as soon as possible to maximize the time that can be used for idling.
