You're really bad at making analogies. It's free additional content. Just like SRL, I didn't have to pay any additional fees to participate in this event. I don't believe I was promised access to any of these events following the purchase of Destiny. I don't have any evidence to support this statement, but I'm pretty sure you don't need Rise of Iron to participate in the Festival of the Lost event either. Festival of the Lost was not something we knew we would be getting when we purchased Destiny.
