Zoom, the video collaboration environment that had such a rapid rise to popularity, was abandoned by many over concerns for privacy and problems with unknown users adding inappropriate content (zoombombing). Although easy to use, these problems caused many educational institutions to look elsewhere (mostly to Google Meet). Large and influential among these educational groups was the New York City school district.
Zoom worked to make adjustments and now encourages users to take advantage of password protected meetings and a virtual waiting room allowing greater control over entry to the meeting. These adjustments have the New York City schools to again endorse Zoom for educational use. The New York City schools have a corporate Zoom account which allows greater security, but password protection and the waiting room are available even to those with a free account.
I admit to being a fan of Zoom. I have used it for online education because it offers useful features and is intuitive to use. I also like to see multiple companies providing online services rather than contributing to what are a few near monopolies.
