The argument has been made by quite a few people that satoshi's alleged stash is a cloud over the market since he could decide to start selling it at any unknown time.
Satoshi could also decide to reinvest his stash back into Bitcoin R&D, education, marketing, bootstrapping, etc.
Imagine the headlines if He started to pay people (in highly-collectible OG Bitcoins) to teach farmers/tutors/doctors/unbanked/emigrants how to use Bitcoin!
I really don't think it will make the "headlines" you're thinking about, when it comes to mainstream news picking up on it... but in the bitcoin community it would be huge news. But why would he pay people to "teach" them how to use his coin? That doesn't really make any sense.
Satoshi could pay people who DO know how to use Bitcoin to teach those who DO NOT. The more the merrier, because of the network effect.
It would make sense financially (as well as ideologically) to spend half his coins on education/outreach if the new user influx at least doubled the value of the remaining half.
The MSM loves a good story, especially ones about our mysterious founder. Should He choose to become the world's wealthiest anonymous philanthropist, the hype would be bigger than Gox+Silkroad+Dorian+$1200ATH put together.
