One of the things that makes Zoom (and for-profit streaming) better is noise cancelation. Zoom has spent a lot of money perfecting video calling without requiring headsets. This is not easy. A second reason is they use some proprietary stream control and compression. It's based on standards and you could copy it, but you would have to license h264 to make this work in open source. Open source requires other people to pay this license (typically it's part of a browser using WebRTC).
