On one hand, it is an example of the total-order mentality which impregnates society, and businesses in general: “there exists a single optimum”. That is wrong on so many levels, especially with regards to charities. ETA: the real world has optimals, not an optimum.

Then it easily becomes a slippery slope of “you are wrong if you are not optimizing”.

ETA: it is very harmful to oneself and to society to think that one is obliged to “do the best”. The ethical rule is “do good and not bad”, no more than that.

Finally, it is a receipt for whatever you want to call it: fascism, communism, totalitarianism… “There is an optimum way, hence if you are not doing it, you must be corrected”.
