Can someone better-versed in legalese explain how this works? What is the restriction before the 12 months (and what happens after that?). Say I make money from the code, what about the contributors? Do they contribute code and get nothing for it, or am I supposed to pay them a cut?

If I'm reading the blog post right, it's essentially MIT for 12 months after you make changes, then (A?)GPL after. (To be clear, not those actual licenses.)
