It seems to have been made by an Internet advertising agency called Purplefeather (their italics) to promote a book about "the power of words". Presumably, the advertisement bit has been trimmed off the end, and it was posted in the hope it goes viral and generates business for Purplefeather. No doubt it has been a success for them.
I don't object to any of that, or to the subject matter, any more than I object to tearjerkers with similar themes of disability at the cinema or on TV. After all, most of those are produced to make money, too. I wouldn't choose to watch them myself, but "weepies" do have their fans.
