The oligarchs hated Kahn with the intensity of a thousand burning suns. If you listened to All In all they were doing is ranting about her and Gary Gensler.

That being said, Kamala's refusal to run on Kahn's record definitely helped cost her the election. She thought she could play footsie with Wall Street and SV by backchanneling that she would fire Kahn, so she felt like she couldn't say anything good about Kahn without upsetting the oligarchs, but what she was doing was really popular.
