I would argue that the Bible is not the only source of hope. I'm sure that our history has provided many real stories that may make such people hope for a better future. I would also argue that they could potentially be false hopes because the promise is salvation is unverifiable. Since these claims are to be taken on faith and not evidence, it's unbelievable.
Also, I think you're being very naive to assume that the picture used accurately portrays the true living conditions there. That picture is used for marketing. That picture is deliberately used to paint a picture to the viewer of how they kids will be when they get the Bible they're supposedly paying for. You shouldn't be taking the scenario depicted in that picture as reality.
PS: BTW, that post doesn't really give a proper description of where the bibles will be sent to, and what the current situation in that place is. So it's not right to assume that they're already being provided with food, water, medicine, education, etc.
