Saying that Twitter expected success is just both a projection and an anthropomorphization on your part. As you are not psychic, and as Twitter is made up of a large number of people, not a person with expectations, you have no way of knowing if any of them expected success as they marketed themselves for more cash.
They either deceived investors or are failures. Take your pick. It's just odd that you can't even understand how someone could see a moral component to it.
