Why is the assumption that it's an either-or thing? We can have responsible parents AND people being outraged at zuck's moneygrab-at-the-expense-of-children move. With this said, I don't exactly understand how an instagram for children can possibly hope to NOT run afoul of COPPA. All it takes is one child uploading a single photo of themselves or their siblings, or referring to a friend by name in a comment, or heck even just using their real name in their username...
