While the dynamic for the physical security of the rich and powerful has changed a bit due to drones, up until recently it was neigh impossible for the common person to threaten the physical security of someone like this, or for nation-states to do so without being noticed.
That meant that the only way to attack these people was a soft attack in the form of social interactions or social media and as such it's always struck me as extremely foolish for these kinds of people to let themselves be preyed upon in this manner.
Like they have teams of people who keep them physically safe, but not mentally safe, so in the age of social media a motivated attacker can, with enough cleverness[0][1] directly reach the mind of someone who otherwise couldn't be reached.
Why does that happen?
I think it's not so much because they're juicy targets that entities with unlimited resources can meticulously target like you describe but because people like Jensen Huang or Bill Gates are very technically competent they probably lack the social skills so they're too often the Michael Scott to the Todd Packer in situations like this[2] and when a hint of opportunity to be sexually promiscuous is presented to them they seize on it without thinking of the consequences.
Think of the married blue collar dudes who pick up bored divorcees at some dive sports bar after watching the big game and then drive home drunk, juggling multiple mistresses and a family life with relative ease for years.
A manager like Jensen Huang may be able to handle multiple business units but he can't manage a single mistress handling his unit because that just isn't his skill set.

Maybe. Or maybe the point of acquiring outsize money and power to many people is to unshackle their experience of the world, and to impose their philosophy on it. Physical security is one thing; I reckon most aren't signing up to be brainwashed for the good of the company (beyond WUSA or whatever).
