they weren't organ "harvesting" in the context of selling organs or implaning them into other people.
These were pathologists who basically felt their medical knowledge gained via autopsy was more important than not desecrating the bodies of reasonably long dead people (i.e. peoples whose organs are not able to be transplanted). They were equal opportunity offenders in terms of jews and non jews (and in practice, many more jews were impacted by it).
It was a huge out cry within Israel due to the desecration of dead bodies.
The use of the term "organ harvesting" is generally referring to organ trafficking. Using the term for unauthorized autopsies is very close to a blood libel.
i.e. to quote wikipedia: https://en.wikipedia.org/wiki/Organ_procurement
Organ procurement (also called organ harvesting) is a surgical procedure that removes organs or tissues for reuse, typically for organ transplantation.
If one doesn't have any evidence that these organs were reused in a manner consistent with that (and it wouldn't make sense for a forensic institute to get anything but long dead people, which would make it difficult) the use of such language is very problematic.
