I don't know what the goal of the conspiracy would be, other than ratings for the "news" corporations, who wanted a big dramatic story with a countdown.
The Navy knew it imploded on the day it happened. Others did too. Why they let this drama play out, and tease the families with false hope? Who knows? The Biden distraction theory is a bridge too far for me. It was a random event that would've gotten huge coverage no matter what, and they only had four days to work with it, before the truth would come out. I don't see some big effort to use it to distract from Hunter Biden's guilty pleas.
It is curious though, as to why they didn't pop the bubble, and why they waited until the very end of the 96 hour window, to announce that the fuckin' thing imploded on the day they went down there. It was like they were waiting for all hope to subside, before announcing they were long dead.
