In fairness (to degeneration) this is the same powerful demographic that pretty much always decides who wins Big Brother.
Think of 16-22 year old women and then their 40ish Mums. They identify whom they perceive as the single women to rally a 'girl power' type of fandom and at the same time identify any 'chauvinist males'. In this case when Kris 'cheated on her' that demographic did (at that moment) give her the win.

It is horrible but they do seem to have done it this way from nearly the beginning and certainly have for the last half a decade.

Again, as odd as this sounds - Sophie was all but assured the win the very moment her fake boyfriend was 'unfaithful'. It all but guaranteed the win.
