This blog post summarizes Mozilla's 2019 Internet Health Report (82 page PDF - note that the report contains many links, but they don't seem to be working in the PDF version, so you'll have to navigate the maze-like HTML presentation to follow them). The report is a "compilation of research and stories (that) explains what’s key to a healthier internet." It's written magazine-style and appears to be as polemic as it does research. It does eventually reach some conclusions, but even these are infused with advocacy. For example, "It seems that if we leave it up to the nine big companies that dominate the field of AI alone, we raise the spectre of a corporate controlled world of surveillance and conformity." Now I happen to agree with this sentiment - but I would not present it as part of an 'Internet Health Report'. I agree less with some of the other policy positions advocated. I'm glad Mozilla takes a stand, but I wish it had been more evidence-based and less rhetorical.
