Well, he looked at the current privacy climate (especially around social media) and thought this was a good idea.
I'd say it's safe to assume he isn't all that socially aware. I can say for sure that I received one of these messages from one of my contacts, I'm damn sure shaming that person back for using this service. I'm thinking twitter/Facebook post naming and shaming, along with an explanation about how that contact was clueless enough to share their whole phone book with this app. I for one don't trust them not to do anything shady with that info.
