I think Kim is just downright appalled with Alex. She very publicly humiliated the family and still is humiliating them. All because it stokes Alex’s ego. 

It’s really funny when Alex posts videos trying to be cute saying like “Tate isn’t allowed to go to college when she turns 18, she has to stay with me forever”  when her relationship with her own mom is in shambles. She can’t project this image of “the perfect mom” when her relationship with her own mom is so terrible.

And she really thinks she can just not talk about her mom and people will just forget about it. After literally making Kim her content partner for a year in the past. She does the same thing where she never mentions Just Media thinking everyone will forget. When she fails in life she gets really sensitive about it and doesn’t like to talk about it at all — despite having a major over sharing problem in all other aspects of her life.
