it’s trusted because it actually works vs terrible solutions like Microsoft Skype, Webex, etc.
The thing that Zoom really has going for it is that it's free and heavily marketed. This made it popular with a lot of people. But it's exactly the people who are least prepared to make an informed decision (and yes, I count a lot on "company men" here). The reasons are sprinkled all over every Zoom article.
You're willing to hand-waive all of the many, many proven, and intentionally hidden major issues with Zoom but you suddenly become worried that Skype works as advertised, poorly as that may be? Would you apply the same principle to your food and taking the one that lies on the label about dangerous ingredients? Or do principles change with accounts?
