We did have an official post today: https://www.blog.google/topics/google-europe/updating-our-ri... that is focused on the improved transparency report rather than the research paper and I am sure it will reach a larger audience. You will recognize the infographic that I borrowed from it :)
When we make a paper public I have the habit to share a short summary (sometime with a delay thus) of what the paper is about on my personal blog. Kurt, Luca and Yuan helped with the summary on a personal capacity which is why they are co-author of the blog post.
Bottom line this is not the official post, we do have one, it is just a summary a few authors of the paper wrote in personal capacity to share some of the finding we found the most interesting.
