As he wrote, he didn't put the game down because he was afraid of the money or didn't want to run a business, he was actually afraid of the effect the "addictiveness" of the game had on some of its users.
With that premise, selling to an established company would have been the most irresponsible thing he could do. After all, the biggest assets of the game are its large user base, the media hype and just that "addictiveness". So this would probably be the first thing any buyer would have exploited, making Dong's problem worse instead of better.
Agree, funny how most comments focus on the money aspect of the conversation. He wanted to feel socially responsible again, did not like the impact that his game had on people's psyche / addictive behaviors and pulled the plug because of it.
In fairness, the three games he's currently working on follow that same mold of being super easy to learn and super hard to beat--not a good recipe for warding off addiction!
You have a point there. The article states he wants to introduce reminders to take a break, though that sounds like the usual excuse feature in such cases.
