I especially can't judge Zoe for going in. Having a 1/14 chance of winning 100K to support her disabled child, when she will (probably) never be able to earn something near that - 50 days away, at most, can be a "fair" sacrifice to a certain extent. It's not ideal, but a mother to a child with medical issues will do everything for her child.
John Partridge went on CBB solely to pay for his dying mother's medical treatments (before she died) when instead he "could've been by her side in her last moments instead of going on a tv show", but it will be a very shallow and unfair way of judging it.
