Probably because if you put them all together, you might achieve the IQ of one, very dim, person. She's no pro manipulator but she does manipulate and fuck, is she relentless.
I imagine behind the scenes there are hysterics and either threats to kill herself or heavy-handed "life's not worth living" stylee bollocks. I'm actually amazed Density managed to escape, especially as in her case there was thwarted toddler ego involved too (AL considered herself above Destiny, she would've been enraged that she was out-manoeuvred) and I'd imagine there was hefty emotional blackmail going on. Amber gets what she wants and fuck everyone else. Dana loved Destiny, it was probably easier to apologise and pretend through gritted teeth rather than see Destiny bombarded and likely worrying Big AL might actually harm herself. Other than, you know, eating herself to death.
Of course she wouldn't, she'd just download the fridge. But that threat, plus she has this army of alleged supporters who message her privately which they may believe in - easier just to issue fake denials and apologies. One day, someone will just fuck her off

but most of those who don't are likely doing it to protect others. Like Rafe didn't give a fuck but Hannah did, so Rafe had to smooth things out.
All part of having zero dignity, I guess. As long as she's seen to be right she's good.
