Almost the whole first page. Maybe angry wasn't the best word, but still I thought people would be excited about this.
Huh. I don't read that the way you do. I don't see anyone who's angry or has negative feelings about DM's Guild content being considered for inclusion in official content.
I just see people irritated that the article that normally gives us mechanical content is not doing that this time. If they hadn't replaced the usual mechanical content offering of UA with a review article, if they had simply added the review as a new article, or added it at the end of a regular UA article, I think people's excitement would be far less muted.
