This is the same company that regularly hosts hackathons and talks about wanting "to inspire young developers to dream up the next generation of amazing products and services, and provide them with the tools to make them a reality."[1]

How about if you want to do that, don't take your users data and hold it hostage to developers who want to provide them a free service?
