Most users care about privacy in the sense that they don't want random people to see their communications. Most people don't care about privacy in the sense that they are concerned about the service provider divulging their communications. Gmail does not use end to end encryption. Yet it's overwhelmingly popular, and perceived to be secure. Google has a huge incentive to keep Gmail secure, and that's enough for most people. With respect to Zoom, I am fully convinced that if the PRC (or the USA for that matter) wants Zoom to compromise a given account they'll do it. But that's irrelevant to the overwhelming majority of people. Sure, companies like Google and Microsoft should not use Zoom nor should activists or other people that might attract the ire of governments that have leverage over Zoom. But that is a substantial minority of use cases.
