I'm not a pilot, aeronautical engineer, physicist, or in any way qualified to assess the validity of the science underpinning the Power Pod, so I won't enter that fray, but I will say that, even back through the iBike Newton, that everything I have seen regarding this type of indirect force measurement has validated its accuracy as a power meter. Are there caveats? Yes, sure. Is it inferior to direct force measurement? Yes, sure, in an absolute sense. Is it inappropriately or ineffective as a training tool? Absolutely not. For most types of general riding and training regimens, it is both accurate and consistent, providing good foundational data.

For cyclists trained enough that drilling down into 10sec data blocks is revealing and instructive, then PowerPod is not the tool for you. But for riders doing 2 minute intervals and 10min blocks at Tempo type training, I have not seen anything to call into question PowerPods utility for such use.
