> How did he went out of his way?
He spent a considerable amount of his free time.
> I have comfortable tech job, I could easily give away few thousands bucks to some charitable cause just to show off (and my quality of life wouldn't change).
Yes, you could. Do you?
> Would that automatically make me a good and trustworthy person? I think the answer here is no.
It wouldn't. But also because there are no good and bad people. There are good and bad actions. I use Linux and absolutely hate what Bill Gates was doing wrt the whole free software ecosystem. I still commend him for his charity work.
> I also guess if for some reason my net worth went up a few orders of magnitude, I could also give few orders of magnitude more.
Yes, you could. Would you though?
