I’m worried your cynicism is overwhelming your capacity for rational thought.

Years of his life and 5-10% of his net worth. That’s the kind of thing people notice.

It's definitely not 10%, more like 3%. His net worth is currently listed as $248B. If he has to pay out the penalty on both acquisitions, his net worth will still be about $240B. There's nothing articulable about the difference in his life as a result.

I will give you the time though, or the motivations (however appalling they are) for his exertion of energy on these.
