Most of the world does not have English as a first language and thus the meaning of the word “gimp” is not widely known. Personally I do agree that the name is dumb, but it’s a very English as a first language issue. My daughter is learning to do basic stuff with GIMP in school because it’s free. The name is not an issue because nobody knows what a gimp is.
I’ll use the cliche meme of “I was today years old when I learned where the name comes from”. Just made the connection when I read this article, and I love Pulp Fiction.
But I too am not a native English speaker. Just always accepted the clunky acronym as the reason for the name.
