Well, it’s a shame for you that the definitions for words don’t care about your feelings.

Do any surface level research on eugenics and it’s always first and foremost about things like forced sterilization/select so called “superior” people for breeding and the like. Even when nazi Germany is mentioned the focus is on forced sterilization and support for the families considered “superior” over those that aren’t.

The ethnic cleansing done in nazi Germany, while used in tandem with eugenics, is its own seperate thing.

They had a reason; money. It’s always about money. The worse the results, the more time you have to spend searching for what you want, the more revenue they can generate.

You can usually trace all decisions a company makes, good or bad, back to money.
