My gods, programmers have gotten lazy. What's next, extra CPU consumption for bold text? The system slowing down every time it beeps?
Or, we could at least allow for the possibility that the behavior was unintentional. If you've never written a program that inadvertently spins a core rather than correctly blocking while waiting for the next event in the event loop, then feel free to cast the first stone, but I imagine most programmers have made that mistake.
