I'm all for this in theory, but in practice I concluded that in October 2016 he was either murdered or exfiltrated to a black site. All the "proofs of life" since then have only gotten more suspicious (a "wedding" with nary a single photo?). Also, a lot of conspiracy theories regarding his status are rendered down to needless controversy and a big waste of time.

Well, maybe that was the point of "keeping him alive".
