Why are we not supposed to like Cynthia Erivo?

So I was on twitter and there was a post about Keke (Lauren) Palmer winning her award at the NAACP awards and saying she didn’t think she’d win because she was up against Cynthia, as she points and smiles at her. Apparently this was a reference to when Whitney Houston did that same motion at an award show. The comments were full of black women saying things like “She didn’t get the reference”, “She’s lost on the nuance of Black American culture”, “Our people are so gracious and we need to cut that ish out” etc. What has Cynthia said or done that caused black Americans to not like her? Also I’m a black American and I didn’t get the Whitney reference till I saw clips and gifs in the comments 🤷🏽‍♀️

Also I hope this is the right flair
