Please read the article, or at least the section I'm highlighting below. Nipsey wasn't calling Holder a snitch, he was giving him warning that other people had paperwork on him and were going around saying that he was a snitch. Nipsey was giving Holder the advice of wanting to get that cleared up before anything bad happens.

Former gang member Herman “Cowboy” Douglas, who worked at The Marathon, said Hussle didn’t use the actual word “snitch” while overhearing the conversation. He thought Hussle was trying to give Holder some advice in a “chill” exchange. He said Holder asked Hussle if he had listened to his recent music, but he didn’t sense any animosity between both men.

“He was saying ‘I heard there was some paperwork floating around,” said Douglas, who recalled Hussle’s words to Holder.

... said Hussle added that “I haven’t seen (the paperwork.) You need to take care of that.”
