I think it's really an interesting discussion to have around those two photos. Before I moved to the Philippines, I might've reacted with the same concern. However, after you start walking through the barrios on a daily basis you end up seeing plenty of young kids not wearing underpants because 1) it's warm 2) it's more economically practical to have kids run around with no pants on until they are toilet trained and 3) there is no outright shame or stigma in seeing naked children. They are simply seen as children. Fortunately, there is a true lack of Western sexualization of children for adult gratification within the culture. As such, what Dave has showed is simply a typical scene that you might see in many of the neighborhoods of the Philippines. Photographs that end up being thought-provoking are usually the ones that have us ask as many questions of ourselves as the subjects we are viewing.
