Pure laziness. At one point he had over $5000 in Patreon money. It's dropped below half that and always dropping. I'm honestly surprised he even has that much. Soon he's gonna have to get off his ass and start working, because his Patreon is slowly drying up. Out of all the CA reviewers, it saddens me to see Spoony having fallen this far.
When he was dealing with his mental disorder and took a short hiatus, that made sense. At one point he was actually pretty competent. Now it's just vlogs, livestreams with little to no commentary, and tweets. Even his last actual reviews were pretty shit. I really wish I knew why he just quit. I really did love his Ultima Retrospective, and still think of it as one of the best video review of a game series.
