You have to wonder how many people were harmed by this fraud. And that's exactly what this is. The original paper was a fraud. No honest mistake can explain it. The reviewers committed fraud by not seeking competent input when they lacked the competence to do the math. How many people under psychological care were given treatments and were harmed? How many companies wasted on money on this and should be able to seek compensation? IANAL, but this smells like litigation.
