Zoom is interesting. I work in IT at the mid-market to enterprise level and sell all things IT (infra, security, cloud, storage, DC) including zoom, webex, msft/cisco teams, etc. There's a lot of concern with companies using or joining a Zoom meeting. Google banned its employees from downloading or taking zoom calls, but I think this is more so because zoom chose oracle cloud over the other cloud providers (azure, gcp, aws). Covid def helped zoom propel, but I think cisco is taking this seriously and will answer. Google is also pushing pretty hard in the web conf market.
