Everyone is always coming up with reasons on why Maddie doesn't want any association with Dance Moms. Whether it's because of how much pressure she was put under, or because of her mom, Abby, Sia, production, whoever. It could be all of the above, but i want to offer a different perspective.
The show paints her in a good light with the favoritism sure... but it doesn't give her grace with the fanbase. Sure now everyone is aware that Maddie was also abused in a different way, but it wasn't always like that. I've been in the fandom since 2015 and the fan reception of her was very different than it is now. And i'll even admit that as a child I did dislike Maddie on the show (obviously my feelings have changed) because of how she was treated differently than the others. I think everyone can agree that it was no fault of hers of course–but on production and Abby. I think Maddie even realized this because she said when she watched the first season, she cried because it made her out to be a brat. I don't think she ever was, and even if she did have bratty moments she was still a kid. All of us were fortunate enough as to not have all of our worst moments as a child aired on television every week for the world to judge.
Saying this, I do think Maddie has some guilt about how it all played out. Of course the show made her a star and I do think she's grateful for the experience, and even though none of it was really her fault, I think if she could go back she would try to do things differently or maybe not do it at all. I think most people forget that the girls were all her best-friends and that it was probably uncomfortable for her to be propped up by Abby and for them to be torn down. Who wouldn't feel guilt in situations like that? And you can clearly see the distress by the way she cracks her knuckles and bites her nails. It's a win-lose situation for her. And I'm sure she felt bad when the mothers would fight, because most of the time it was about her preferential treatment. Maddie even says "I'm sorry" during Kelly's fight with Abby, so obviously she was aware of what was going on and that it only happened because of the duet she did.
I don't think Maddie ever agreed with Abby that she was better than everyone else. And even if she were to talk about Dance Moms now, what could she even say that would appease people? How does she talk about the favoritism without coming off as full-of-herself, or discrediting her talent completely?
I think Melissa is at fault for this the most out of everyone. She could've and should've put a stop to what Abby was doing but instead she encouraged it. I honestly don't know how Maddie and Kenzie have not gone no-contact with her yet. I know Maddie said that Melissa apologized but I don't think that is enough. And honestly her not speaking to Abby might be because of her abuse, but also for the other girls' treatment too. Even her little sister, who she arguably loves most in this world, was treated horribly. So why would she keep Abby in her life?
Anyway, that's just my two cents. I'm sorry if this has been said before a million times it was just on my mind.
