I think they already knew they were compromised and our adversaries had this blackmail information (possibly already used it on our government) and they had to get it all public before the election was stolen for Biden. They were trying to clean up Biden. The deepstate probably said, "hey Biden, you are compromised, you're going to have to come clean with the blackmail material." You can't use it for blackmail if it is made public. Also serves as a "shiny object" to distract from the voter fraud operation.
