I'm too tired to respond to the entire post but this part is silly.
That's 3%... and I'm frankly insulted that you think that TotalBiscuit cares about the viewcount on his video in specific. As long as people see it he's happy. People will draw their own conclusions about the video whether or not there's commentary overtop it, which is what the streamers are doing. On top of that, I don't appreciate that you don't want people being the devil's advocate to the video either. All opinions are to be considered, listened to, and picked apart if necessary.
I haven't even watched the video yet, keep that in mind, but once I do watch it tomorrow I'm going to give my opinion on both the video and the video+commentary. If you want your opinion on the commentary to be taken seriously then you need to take it seriously yourself, and actually consider what they're saying bit by bit, not by what their apparent tone of voice is.
You wouldn't agree that re-broadcasting another person's video is unethical? Personally I'd be furious, but I guess you're right, TB has bigger and better things to worry about.
I can't address the rest of your post, I have a raging headache and it's like 11 PM, but I will later.
I would like to note that one of KingofPol's moderators is running a "Times Totilo Lied" counter in the chat. That plus the shoutfest of the comments in general are a pretty good indication of what this commentary, regardless of merit, is breeding. I did actually watch a bit more of it after your post, and he does seem more calm and composed now, with actual opinions being laid out, but still, I think the best way to bring GG to an end is what TB is doing, and trying to bring together people that can discuss issues and try to come to conclusions that will help end this stufffest.
