Courts will argue about the legality long after I'm dead but for me right now this is an agreement I propose, if you want to see it in your own way go ahead, I'm not going to sue you; but history will look at your existence in a bad way how ever you squirm from the fact that I'm saying: "Use this for free with MIT _OR_ if you want to make money, share some of it." - You can't get away from that...
This is my last answer to these "but MIT is free", "ALGPL does not exist" kind of comments, nothing exists except your conscience... do what you want!
