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.

The point I'm trying to make is that people at this level can and often do have absolute physical security but have almost comical[0] lapses in psychological/mental security that lead to the kinds of things that you're describing.
The severity of this issue makes me wonder why it seemingly isn't accounted for appropriately in security threat modelling. You'd think that that the handlers for a dweeb like Huang or Gates would take the appropriate steps to mitigate the threat, if only by adopting harm-reduction principles and getting their CEO an in-house honey pot to proactively fend off external threats.
