That's not what's said. It's blaming people for being negative when we haven't seen much of the game yet. With any developer you'd give them a shot to show their gameplay and then form an opinion. If you have a couple of bad experiences with a studio and want to be negative, that's legitimate criticism. This studio is new, watch some gameplay before dismissing them.
No one's making any promises about buying or not buying their game.
However, positivity and faith are earned, and neither this game nor their dev have earned anything so far.
