I think you underestimate MS Teams marketshare. If I'm not mistaken, I've read somewhere Zoom is loosing ground with each Q to competitors. But MS dominates now, for sure. Also worth pointing out, almost none of these online conferencing products were "alternatives to X". They all had their own unique propositions. Superior video quality and streaming, collaboration tools etc. Those who build "alternatives" - fail.
