Instead, this story alleges: (1) the reporter planned to meet with a source to get a classified leak, (2) the FBI got wind of it, and (3) they planned what amounts to a sting operation (I guess, it's complicated because this was in France) to catch the leaker.
That's... I mean that's the FBI's job. That leak is clearly illegal, it's a crime. Their job is to enforce the law.
Beyond that there's some juicy details about the lawyer who originally ratted on the source and then got cold feet and warned the reporter. And that's interesting.
But... there's no government abuse angle here, not without knowing the contents of that leak that didn't happen.
