The Manon being lazy bit, they already tried to spin during the Youtube series and it got her a lot of hate. A lot of people were against her (but she also had a dedicated fanbase from the start!) until Samara left, because people were so fixated on "the perfect balance" of ethnicities in the final group. This drags these same people back up.
I like Manon but it's obvious she wasn't taking it as seriously as other contestants. She said it herself. They all talked it out and moved on from it, from the clips I've seen, so why are fans so enraged?
