Non-free software advertisement presented by your government What would you think about a sign on the highway saying “You need a Volkswagen to drive on this road. Contact your Volkswagen dealer for a gratis test drive – Your Government”? When it comes to software that opens PDF files, many public sector organisations do this every day. With the pdfreaders.org campaign FSFE has turned the spotlight on government organisations who behave in this way, exposing how frequent such advertisements for non-free software are. With the help of activists across Europe, FSFE contacted these organisations and explained them how to improve their websites so that they respect our freedom. Until now 511 out of 2081 (24%) reported public websites have fixed this bug https://fsfe.org/campaigns/pdfreaders/buglist.en.html. 58 organisations, 56 buisinesses, and 1938 individuals have signed the petition https://fsfe.org/campaigns/pdfreaders/petition.en.html. This presentation also serves as a short guide how to get active in the campaign yourself. https://fsfe.org/campaigns/pdfreaders/
