Just to be clear, I never said that the word should be banned.
I am not sure how important the German or general European market is so hard to say whether it even should be a consideration for Grammarly.
That said the ideas of some people being intrinsically better than other people isn't specific to Germany. Eugenics used to be popular in many countries including the US. It is very advisable for other countries to learn from German history so our mistakes are not repeated.

I'm sure a large population of second language English speakers is a huge market for grammarly, no?
