The vibe I got from Carmack after reading Masters of Doom recently is that he's never had a big focus on money. When they struck it rich he certainly divulged himself in a few luxuries - going a bit more extravagant on his nerdy hobbies, decking out a Ferrari, building rockets. But he still seemed to mostly just want to do his programming work, and that seems to be what he's continued to do after all these years. So it doesn't entirely surprise me he was willing to be generous with his money like that.
