I've unsubbed, mainly because of his lack of concern for those that were paying. He never said anything publicly (that I know of) about his lack of posts, and the quality of posts he started up with were terrible.
Has it gotten better since? Possibly, no one's posted anything. Did he change his mind about doing different content? Sounds like it, and that's his right. But it's also our right not to pay for crap quality and lack luster content that's worse than what he's posting for free.
Just my 2 cents.
