The posts depicted meetings of various military people and they would have been told what to say.
Too late now for them to deboonk it definitively. He may resurface on TV later but that would not prove he was not captured.
This story will live on as an amusing and highly plausible rumor on social media.
It is unlikely that there will ever be a public video showing him captured or anything conclusively proving such. It is highly embarrassing for the US if it actually occurred and they would undoubtedly offer additional concessions to keep it officially secret.
If they negotiate for his release they could easily have him back in Turkey and have him appear on TV very quickly. It seems like they can successfully prevent the rumor spreading long enough for them to negotiate for his release, assuming he is alive.
However, since no conclusive deboonking has happened so far, it is too late to definitively deboonk it since any subsequent videos would not prove he was never in captivity.
Later rumors have appeared including that 1 - he is dead 2 - he is still trapped among the Azov
In addition to that, various Ukrainian government officials have claimed success in a helicopter mission. This is very unlikely to have actually happened, but it could either be a fake for morale boosting or alternately cover for NATO paying a ransom or whatever concessions demanded.
We will most likely never see definitive evidence on this issue but IMO the mass bans on social media plus lack of an official US government denial would suggest the story is true.
His social media accounts apparently made a post claiming that he was in Turkey and that is the sole public evidence to the contrary. In this situation a social media post is not proof of anything since the US government could easily seize his accounts.
The two suicide mission helicopter rescues by the Elenssky regime also are suggestive that there are important individuals trapped in Mariupol.
His friend Henry made a video about escaping after Thanos destroyed the Avengers training camp.

The CanadianUkrain1 account appears to be connected with the earlier “JamesVasquez1974” account which posted the viral “welcome to america” video. They are quite likely operated by the same person.

This video by Gonzalo shows the usage of the photo stage set featuring the destroyed (Ukrainian) tanks, which were featured in various videos. It may suggest whoever is operating the accounts has permission of the government officials.
It does however seem quite unusual for a government to be begging for donations from Twitter liberals and I thought Sleepy Joe had given then 33 billion. Maybe the propagandist is being paid by tips?
