How hard would it be to tweet that "yeah, it's possible to find someone. It's just a bug. We're working on it." I mean, the devs should probably know the features in their game, right? They don't have to explain the technical aspects of it if it's launch day issues or something.
On the other hand, if they were bullshitting and just got caught way faster than expected, I can imagine it taking them some time to come up with a deflection to try and escape the negativity without admitting fault.
Still, I'm not sure why people should give an entity focused on maximizing profit the benefit of the doubt. People can, and should, raise the question and indicate their displeasure, but in a reasonable and adult fashion. Bombing his Twitter with "fuk you, lier!!!" isn't what people should be doing, obviously.
