Amber did not make a cent on interviews or articles at the time she could have made the most. That is between the time when the police announced her presence in Scott's life and April when Laci was found. And later, before Laci was found and the court. It was not forbidden, her coworkers sold their stories about her. But not Amber. At first, she hoped that Laci would be found, and later, when she believed that Laci was dead, she did want to neggatively affect the court process. So, she did not make half of the money she could have.
Most people she ever met were supportive of her because her actions were dictated by compassion.
BTW, Scott complained of his share of one-night stands and bimbos during Laci's pregnancy, so I doubt that him killing Laci had much to do with Amber. It had a lot to do with Laci's life policy that he cashed on, and he did not want own child. Ever.
