It's true they no longer officially control the FBI, but their use of blackmail did not start with the FBI files and it certainly didn't stop there.
Many Arkansas troopers have told of Governor Bill telling them to see if they could "find some dirt on" whoever was annoying him at the time. The Clintons also employ PI firms to do "opposition research" which isn't necessarily illegal depending on how you use the info that gets dug up. Blackmail and extortion are still illegal at least for a while.
One of their blackmail producers and occasional thug service providers is now in jail. A lot of people were hoping he'd turn on them, but IMO he knows better than most what would happen to him if he did.
We know about CREW and Media Matters search for and use of timely dirt. When they can't find any, Media Matters sometimes tries to generate it against honest talk show hosts. In fact we have no idea how many blackmail factories the Clintons actually have running, but I hope it blows up in their faces.
They also probably still have minions in the FBI that will be sending them any file or update they need.
