This 2019 article by the Times is a good example of just how much we knew about Hunter Biden's issues prior to this document dump. Along with being of questionable provenance, these new files don't really add much to the story. https://twitter.com/kausmickey/status/1317919112463409152

We already knew that Hunter Biden had drug issues, foreign business ties, high salary despite low experience, and that he introduced one associate to his dad. This stuff is real, important, and not based on a potential hack.

In light of that, it's clear the bigger story stemming from the document dump is how exactly Rudy Giuliani got his hands on some of Hunter Biden's private files.
