The coronavirus pandemic pushed people to stay in their homes, and in turn, forced them to use video conferencing products. In the past couple of months, Zoom became an almost indispensable app, Facebook had to step up and make a rival product, and Google made its enterprise conferencing product free for everyone.

Amid this video conferencing boom, Zoom’s security and privacy-related problems made a lot of people skeptical about using its products. Plus, the company wasn’t transparent about communicating its mishaps — this forced a lot of people to look for free open source products, and Jitsi emerged as a perfect solution for them.
