The problem is not with the use of data to make decisions - the problem is with the simplistic one-dimensional use of data to make decisions. Instead of attacking the data - which leaves you with no ground to stand upon - it makes more sense to attack the simple-mindedness.

Change the grounds! It’s not that their approach is ‘data-driven’ or ‘evidence-based’ and yours is not, it’s that they have very carefully selected a subset of the evidence that will ‘count’, while you are using a much broader, richer, and ultimately more accurate base of evidence.
