My two cents
"The 'empty stomach' line is clearly insensitive and didn't pass by a (human) editor."
That line was lifted almost verbatim from the Ottawa Food Bank website - apart from changing "imagine" to "consider", so the criticism of that wording is somewhat unfounded.
Agreed, I would not want this turned into a "tourist attraction" for people to gawp at - OTOH, if it makes people aware that there are needy families everywhere (Ottawa, Canberra, London, etc, etc) maybe that is a good thing, especially if people divert some of their holiday money from overpriced museums to turn up with a food donation.
