I don't see what's the fuss about it.
In every gaming company there are people (plural) that work on some project, so if someone leaves (or dies) he is replaced by other member from the company or new person is employed to fill that spot.
Game servers are up as long there is enough players interested in a game and it's profitable enough for game company to maintain them. Hampa or no Hampa, if Nabi were losing money on Toribash they would close it long time ago.
