I think there is a possibility for the "self fulfilling prophecy" in this situation. People start fearing that the game will not be made, so they demand a refund. Enough people do this and the company folds.
Also, all the bad press keeps people on the sidelines instead of in line.
Doubt communication would make much of a difference at this point. "Words are Wind" as they say on the Game of Thrones. The best way to allay fears is to get some games out.
If the game is decent, I expect people will be lining up again.
