That nobody would give crap the first about some white-collar crime involving dodgy accounting, if it wasn't for some salacious backstory, is a sad indictment of the public at large, and of the media that stoke their desires for sex and outrage (ideally both at once).
But the sex is just the reason this sells newspapers; It's irrelevant to the reason his actions were criminal, and it ought (in a sane society) to be irrelevant to literally anything - unless there's a suggestion of non-consent, which would make it a crime in its own right.
