I don't feel a "dark aura", but I do feel this story is irrelevant to your product's marketing page. I'd put this story away (maybe in a blog post) from newcomers who only want to figure out what's the app can do for them, not for you.
I agree, I think the story definitely belongs in a blog post. It's a good story, and you're building the company for a good cause, but it's not what you should put on your front page.
+1. I also feel this should belong to a blog post about the creator(s)/behind the scenes than on the front page showcasing your work. It looks like asking for sympathy votes that way.
