In the days of physical isolation, technology for remote communication has become crucial. More than ever, we need secure and ethical technologies to stay in touch.
Unfortunately, commonly used proprietary teleconferencing software such as Zoom and Skype are unethical and have serious issues.
The major problem with such programs is that proprietary software can not be trusted. Proprietary software is intrinsically insecure due to lack of transparency and possibility of independent audit. "Black box" approach is neither safe nor ethical.
We encourage the use of Free/Libre and Open Source communication software.
