From 1:14:55-1:15:20, within the span of 25 seconds, the way Demis spoke about releasing all known sequences without a shred of doubt was so amazing to see. There wasn't a single second where he worried about the business side of it (profits, earnings, shareholders, investors) —he just knew it had to be open source for the betterment of the world. Gave me goosebumps. I watched that on repeat for more than 10 times.
Still great of them to do, and as can be seen it's worth it as a marketing move.
I think it's more about someone trying to do the most good that was possible at that time.
I doubt he cares much about prizes or money at this point.
He doesn't have to care much about prizes or money at this point: he won his prize and he gets all the hardware and talent he needs.
