Because the security / privacy focused video conferencing apps are getting no traction. Because the tradeoffs for security / privacy (more difficult onboarding for an individual on new devices, more difficult inviting, poorer video quality etc) seem to have scared people away from those options (which do exist) and into the arms of zoom which has made ease of use it's entire focus.
You can set your own meeting room to be join-able BY ANYONE with an ID that DOES NOT CHANGE. Terrible security - great convenience.
Business and educators get feedback if students etc are using other programs other than zoom while on call. TERRIBLE for privacy (zoom tracking which windows are foreground etc) - nice convenience for teachers and bosses who like this.
At every turn, zoom has emphasized things like this.
