So idubbz is disappointed that Sam is not like a modern celeb/entertainer with a personal presence and is "confused" as to why he'd choose to keep his private life and motivations private like a pre-internet classic entertainer. He's also disappointed that he wasn't allowed to be part of his friends' group.
And that's a "detriment" to Sam (as idubbz said), why? Does idubbz seriously believe that since MDE content is on a social platform that he as a fellow content creator deserves unfettered access to everything about him and the fans deserve it too?
E: I also feel like idubbz could have easily used all the shot content to make a mockumentary style video after the prank was revealed, or have it be some other type of project instead of just admitting defeat on his primary purpose nad making himself look like a chump
