Because this is an open forum. If you act like not getting a code is the end of the world and feel you're entitled to a code and express that feeling openly, you run the risk of people actually responding to you that may not agree with you.Why is everyone complaining about everyone complaining? It's a form of expression! Let it out, imo. You're all right about favouritism. But there's nothing that can be done about that. It exists everywhere. The beta is long from over yet. You'll have your chance.
Like I have no problem admitting I'm an asshole, I own that. But seriously, y'all can't be surprised that people see the "end of the world" complaining as ridiculous.
Anyone can complain about anything, but your complaints aren't free from scrutiny. Just as mine aren't.
