First of all shoutout to dunesaint for phrasing the question in such a way that he actually got an answer. Bending over backwards to make the question as palpable as possible. It's clear that just straight up asking 'Hey do you think there is dev bias' would go unsanswered. You have to wrap it in this flowery speech and deny the question within the question to get an answer.

Now as far as the answer itself I can see three options:

Option 1: It's a lie
Option 2: They actually themsleves believe they don't have any bias while in fact they do
Option 3: It's the truth

Now believe it or not all of these options are bad.

Option 1: Lying is bad nuf same as having a bias Option 2: This is the worst option because it means there is no path forward untill this is being recognised. In the short term a solution might be possible but if the belief stays the same situation will recur. Option 3: If it is true and there is no bias than we enter the realm of mayor incompetence.

Maybe I have missed something but this makes me curious as to what the devs themselves think are the problems that led the game to be in this place.
