Yes, the number is silly. But that makes the danger even more relevant. They could really get it for a couple million to a couple of people, and double or triple that payment (or stretch it out over a long period) to make sure everybody knows to shut up about it.
(Taking this reply as an excuse to write a concurring rant...)
Also, once you've compromised somebody's integrity and got them on the payroll, why not use them for other things? They can join other projects, they can sit on foundation boards, they can become tech media personalities, etc., etc....
There's nothing tinfoil about this. It's cheap and easy. You could subvert every open source project in the world for less than the cost of one fancy plane, or a few fancy missiles. The CIA went in on a crypto company, got it to weaken everyone's crypto, and likely killed the son who inherited it from the previous owner. "Nation-state buying Little Snitch" is not some crazy fantasy, it's a mundane scenario (I'm sounding like LLM today, I think.) Even though OpenSnitch could be compromised even more cheaply, they show all their code.
Also, aggressors don't just use carrots, they use sticks. The Altman sister stuff for example (true or not, works even better if it's true) certainly seems like a stick. Top of the world, then suddenly a jury (easily subverted by a state) puts you in prison or takes away control of your company, and now you're killed (or "kill yourself") in prison or otherwise. Now your widower and your sister own the company, and they say yes to everything. If my multi-billionaire brother molested me, you'd never hear about it because he would have trivially given me enough money to forget about it and him. I wouldn't be filing any lawsuit. Makes me suspect that he's being resistant to something.
