Looking around the rebuttals[0][1][2] seem pretty non-exceptional. From the looks of it nobody's claiming Wilson's math is incorrect on a technical level, but that it's wrong on a conceptual level. Taleb's mathematical audit may have preemptively refuted a claim nobody was even making.
If Wilson et al. have a better tool it's on them to demonstrate it. Nobody needs to check the math, they just state their better predictions and the community examines them. Sometimes the claimed mathematical tools aren't even as good as the current ones, and then the correctness of the math is moot. FWICT, the biologists are saying they already have better tools and they're declining the offer to downgrade.
