In a time when humanity needs to work together to find solutions for a crisis, we cannot afford to reinvent the wheel again and again. Global problems need global solutions! It is Free Software that enables global cooperation for code development. Any proprietary solution will inevitably lead to countless isolated solutions and waste energy and time which we as humanity cannot afford in such a critical situation. Free Software licences allow sharing of code in any jurisdiction. Solutions developed in one country can be reused and adapted in another one. Already before this crisis hundreds of organisations and tens of thousands of people signed an open letter "Public Money? Public Code!" and demanded that publicly financed software developed for the public sector must be made publicly available under Free Software licences. It is now even more important than ever before to tackle this crisis.
