We call on the Government of Ecuador to immediately and unconditionally release Ola Bini and to drop all charges against him. As technologists, free and open source developers, individuals and organizations working to protect the security of the Internet, we oppose the continuing illegal detention in Ecuador of Ola Bini, a cyber-security expert, privacy consultant, free software contributor and advocate of digital rights. We see his ongoing, preventive detention as arbitrary and as an attack against us all. Ola Bini is a cybersecurity expert and privacy consultant in the field of Free and open source software, as well as a defender of digital rights. He is a Swedish national, living with a valid permit in Ecuador for six years. He is a prolific contributor to a long list of projects, among them OTRv4 and JRuby, and is a member of the advisory board of the flagship European project DECODE (grant nr 732546) on advanced cryptographic and privacy by design research In addition to violating his basic human rights, his continuing detention negatively affects this important work.
