Check the update when bungie said they can now change things using dev tools. They can change xur. edit: Ive read your edits and those are also some horrible reasons why xur would sell it. luck /=/ rng Xur can control the population just like when he sold TLW the first time. PvP was nothing but TLW. And probably brought back most players who left. Just saying it could happen to Ghorn when destiny gets low on players.
