One of the best ways to guarantee a game dies is to spread gloom and doom about a possible shutdown (even when nothing has been mentioned about it); it naturally occurs then that people will be wary of spending their time and money on the game and if it persists the game will indeed be shut down due to the lack of interest and profit.
It's a self-fulfilling prophecy.
That said, Eab isn't wrong in that FKG isn't safe. No online game ever is safe and one should never spend money on an online game without bearing in mind that ultimately you will be left with nothing to show for the investment.
Also Nutaku needs to get their shit together and realize at some point how much self-harm they're inflicting by closing down games so often; churn isn't a good or sustainable business model.
