@Nesh I think you're looking at it through an interesting filter. To me, I saw the OG logo, I immediately knew what it probably meant and the crowd did as well. They began cheering for their beloved OG logo - the same way Miami Dolphins fans cheer for their throwback uniforms that Dan Marino wore when the Dolphins were "good". It's a memory of the good ole days. The fact that they continued to cheer without knowing what exactly they were cheering for doesn't provide enough evidence to jump the conclusion that they were somehow planted or falsely encouraged.
Of course, if one was prone to believe the entire show as farcical then I'm assuming that a crowd reaction that doesn't generate a similar emotional reaction in them would be immediately greeted with suspicion. For me, I thought it was cool, even though I have no use for OG BC. I still thought it and the subsequent release of The Duke, was one of the best parts of the show it brought back fond memories of playing Halo couch co-op and helped remind me that at one time, I enjoyed playing on the Xbox.
