That's the actual objective of the whole story: she wants the money, for herself, and her children. But Bill Gates had already pledged that money to charity. So she had to find a good excuse to get the money out. This is it.
Of course, once you divorce and become the richest woman on Earth, just from being married to the right guy, it's bound to attract scrutiny, so let's find a good escape and scapegoat. And in these days and age, what's better than blaming a rich white male, favorite scape goat of our times with zero redeeming chances on the horizon, not even after pledging his entire fortune to charity !
So here we are : Bill "had an affair", 20 years ago. Yeah. But somehow, this is now that it's horrible to recall. Maybe the period coincides with the monopoly trial. Likely a tense situation. But who cares.
Bill "knew Jeffrey Epstein". Sure, these days, it's an absolute sure blow. Well, Epstein also knew essentially everybody with money and power in US, but hey, no, let's phrase that as if it was a personal and deep connection, like, probably he was providing some under-aged "services" to her husband. Sure, she never said that. Just implied. Deniably.
And while the word is occupied blaming a rich white male, the world does not get to see that charity organizations now have 50 B$ less to use over the next few decades, so that a poor, poor, horribly traumatized but now Extremely Rich white woman can scam away with the money and transmit it tax free to her children through multiple offshore expert schemes.
But hey, that's not the story ! Too booooring ! Look, look ! Epstein here !
