I understand your point, but need to disagree: PR-friendliness can have real-world implications, such as a stronger negative response of Zoom users.
Another important thing to consider: Zoom is probably aware of the risks involved in this decision and, despite the PR risks, decided to go ahead. Why? Most of us here can come up with a couple of reasons.
That, and most zoom users don't care. We use zoom at work, in spite of my repeated warnings to the contrary and my efforts (and demonstrations) of Jitsi. But they like zoom. It's convenient. It's sort of cross platform, and when it isn't, you can just dial in using a phone.
Plot twist? The company I work for is a software company. We're all software engineers. And yet I'm unable to make them have a negative response to zoom. I can't imagine the greater public giving an iota.
