Exactly. "Ownership" is not easily defined when it comes to content. For all we know, just because Rob appears in the video does not mean he owns the rights to the content. And just because the guy who uploaded the content is not in the video doesn't mean he might not have connections with people who own the content. Just saying.
And this is all because ownership beyond "I made it I own it" is hidden in contracts which arent required to be public. People who expect third parties to have knowledge of private contracts are making unreasonable claims.
