He co-authored a report, which is something more than an opinion. It may be used to inspire policy. There should be greater reputational consequences for publishing something you spent a few months studying and writing about along with several experts. Just my opinion.
I don't understand what you're trying to imply here. Yes, he co-authored a report. What is supposed to be dangerous or suspicious about this? What does your statement about "reputational consequences" have to do with your original comment, which implies that this some indicates a bias on his part?
It seems to me like you're trying to somehow imply that writing things to convince people of what you believe is somehow nefarious? It isn't! It's what we're all doing here right now! Putting it in a format that certain people will take more seriously doesn't make it nefarious either. I am quite confused by your point of view here.
