The grandparent provided an argument why we might not want to use an algorithm, even if it provided a Pareto improvement.
I suggested that the same argument could be used to say that we should actively degrade performance of the algorithm, in the name of equity. This is absurd, and illustrates that the GP argument is maybe not as strong as it appears.
The argument doesn't make sense in practice. We could discuss it as a philosophy exercise, but realistically if the current result is better overall and biased against some group, you can just rebalance it and still get an overall better result compared to status quo.
Changing codecs in practice takes years/decades, so you always have time to stop, think and tweak things.
