It's because we care too much (tear). When it looks like the developers don't, that doesn't sit well with extreme fans like you have here. It feels like we care and treasure the franchise more than the people in charge of it do. I'm a MP guy, but I can totally relate to these guys who get pissed about "jokes" determining the In-Game Fiction.
When you guys laugh and joke about stuff that negatively affects us players, we dislike it. It's funny when the game is good, not so much when it's not. When you ruin MP and your only response is "IT GUN B K" and half-truths and empty promises in the bulletin, it makes us want to lash out at you in return. When you make it seem like the conclusions to the campaign is a joke, people don't like it. Even though most of us realize that making a game isn't so simple and straightforward, we still want you to at least give us the courtesy of explaining some of the major rationalizations.
Do you know why the Great Wizard of Oz was such a disappointment? Because he was a farce hiding behind a facade. He wasn't the man everyone expected and wanted him to be. When the great and powerful 343 reveals itself and all we see is a bunch of clowns shitting on our most treasured franchise and joking about it, even if they really do take it very seriously, it makes us sad and angry.
Think of politics. How often have you screamed inside at a politician begging them to just be straight with you, just tell the truth and explain it like an adult. That's how we feel.
If you're going to reveal the men and women behind the curtain, just tell us the straight truth about how and why decisions were made. You can color it with your jokes and the hilarity of the workplace environment, but unless that's really how the decisions were made, that's not where the revelations should end. You did a little of it in your post I quoted, and you know what, that tiny bit was more informative than any of the bulletins I've read so far.
I'm not posting this with any animosity or ill-will towards you or 343; I'm beyond that. I respect you enough to offer my insight and all we ask is that you do the same to us.
