He was basically an egocentric and vaguely sexist guy who never really validated duna (mc from the main story) and would always insult her writing instead of encouraging her. She said that the final straw was when minho claimed to be the reason why her best selling book was good. All of it really happened like 10 years ago in the story's timeline and he didnt really do anything in the current timeline of the stpry to even warrant at least half of what happened to him in the main story so i can understand translator's frustrations (and i also agree with them. I feel like minho is just treated as a punching bag and a subhuman)
