The cover subverts the foundation's vision statement, "Image a world in which every single human being can freely share in the sum of all knowledge" with strikethroughs representing the danger censorship poses to that vision. Don't worry, this censorship is easily scratched off.
The significance of issues like government requests for user data is illustrated with relevant quotes at the start of each report section.
Data enthusiasts (of which there are many in the Wikimedian community) will find a fold-out insert of stats from the past year, clearly presented in clean, colorful text, tables, and graphics at the end of the report.
This report was an exciting opportunity to help folks doing amazing work communicate why it matters. I also had the added pleasure of watching these fly off the tables at Wikimania 2017.
