Matthias Kirschner is President of FSFE. Matthias helps other organizations, companies, and public administrations to understand how they can benefit from Free Software -- which gives everybody the rights to use, study, share, and improve software -- and how those rights help to support freedom of speech, press, and privacy. He serves on the advisory boards of different Free Software organizations, has been a consultant for public bodies and other committees, and regularly gives interviews, lectures, or participates in panel discussions about software freedom and the technical distribution of power in a democratic society.
