I did, and from what I heard, it is a big myth that the results were actually as useful as the first assessment on discovery of them had been. Later studies have, as far as I know, been much more sobering as to the "usefulness" of the data acquired there.

The website you link also immediately shows the problem (even in presentation, presenting them quite sensationalist, immediately highlighting, that there is no possibility of neutrality in assessing the results): The "cruelty for cruelty's sake" in the conditions of the experiments cannot easily be removed from the results. Making the data in the end only useful for very specific circumstances, and hard to untangle. Lets take venereal diseases for example - it ultimately shows how they spread and interact in conditions of forced mass rape under conditions of extreme squalor, as documented by people not engaged in proper double-blind environments. The usefulness of that is not as high as the myth surrounding Unit 731 or Mengele's experiments might suggest - and as your linked website also shows, there is a material interest in selling that myth of "forbidden, evil experiments resulting in knowledge".
