>>10412522She was genuinely emotionally attached to Mori. Whether that is friendship/admiration or romantic feelings I don't know, but I will say that it's very hard for me to believe it wasn't romantic.
After she traveled back home she was suffering about missing Mori for quite some time. Then something happened. Suddenly she wasn't suffering anymore, and suddenly she wasn't simping for Mori anymore. It was clear that the emotional attachment she used to have was gone.
So that's what happened and that's what she meant with "things change". She simply got over Mori. Once you're no longer emotionally compromised you have a different perspective. For one, it would become immediately obvious to her that the entire ship lives and breathes on HER initiation, so how could it ever survive if she doesn't care anymore? All the other reason she listed are just things that are safe to mention publicly, but clearly not the root of what happened.
The normies who think Kiara sat down with Mori in discord and made some calculated decision of ending TakaMori, like "you know what, let's end the TakaMori stream, because FREEDUMS and stuff", are completely ignorant.
