Christ, some people are dumb.
How do people propose he try to get more money for it? Blackmail Blizzard, or sell it off to private buyers? Because you can bet Blizzard would have sued the fuck out of him if he tried either. Putting up a business' insider secrets for sale is a big fucking no-no, regardless of how you come into possession of them.
There is a possibility he could have been more shrewd to begin with and tried to find possible collectors. Someone in the world would pay decent money for this. And not everyone would have nefarious intent.
Saying that, you'd need to find them first, which would take a lot of work especially while trying to stay anonymous throughout.
And the IP is still active, which makes the moral angle tighter.
Personally, I would have handed it back and made a copy. Not to do anything with necessarily, but I'm not sure I could just say good bye to the wealth of information.
The guy did the right thing in terms of morals, imo. The active IP part seals it. If this were an historic game that wasn't still being developed then I'd disagree.
Besides, he'd already announced himself. At that point people were asking him to potentially sacrifice his future for software preservation, calling him selfish for that is pretty ironic.
I'm just hoping he doesn't become a target for maliciousness like doxing etc... now people are angry with him. Some of the responses on reddit are pretty sickening even if the preservation angle has merit.
Guy should sit back, enjoy the swag, and be excited for Blizcon. They're probably going to load him up with swag when he leaves there, too, plus he could make some invaluable connections that serve him for the rest of his life/career.
Guy did the right thing, all things considered.
