Well, I don't think we can call it a theory. Like I stated in my post, one staff member leaving then sure we can say he's moving on to better working opportunities. The amount of staff leaving, then no way. They haven't stepped down because of what they stated in public. Though being professional about it that's the reason they have given. Hat's off to them for that.
Either way, that's the way the cookie crumbles unfortunately. Let's just look forward to another bloated, featureless version because any other reaction and your liable to be hanged.
