As much as I think Hazno is to blame as much as the ILBW for all the lies and plots against TRF, I think that definitely the ILBW is the worse for their branding as a couple. We see the Kelce brothers talk about the Wales family and I am thinking they might have liked Hazno have they met him alone. But we know that if they have met the ILBW she wouldn't be called the "coolest" anything. The ILBW has made herself very dislikable. She has a thirst for fame and attention that makes her behaviour aggressive to anyone who may be perceived as more important.
We saw this after the polo match when she pushed the lady from Sentebale on stage, assuring that the ILBW would be front and centre of all photographs, we saw it in Nigeria where she cared little about those she was visiting, I saw her making no questions, showing no interest, always talking about herself. We saw it, cringing, in the Kevin Costner event, grabbing the mic like a mad woman. We even saw it in the real Royal Tours before they went to America, where for someone who had allegedly been silenced, the ILBW gave more speeches (where she a) constantly talked about herself and b) lied) than I remember Catherine ever giving.
In the end, she has no curiosity for others, as in her universe others exist only to praise and validate her. The Kelce brothers mentioned how adorable Charlotte was asking questions, being interested in others and not focused on herself. This is what she sees her parents doing. This is what makes the PPOW liked and admired by all those who meet them.
And this is exactly why, no matter how many rebranding she goes through, the ILBW will never be a worthy brand - and there are no jams and dog food in this world to change this.
