You are clutching at straws here. Zoom fires an alert when somebody joins a meeting. If you're not paying attention, that's not Zoom's problem. If the alert isn't surfaced very well, that's an UX issue, but not a creepy privacy invasion. And if you expect to be able to use a platform which your employer has provided without any oversight whatsoever, I don't even know what sort of problem that is. Do you also expect to be able to lock the door to a physical meeting room, on your employer's property, and use it for your own private purposes unchallenged?

So, what better UX do you propose? Playing a sound of a squeaky door?

On the other hand, I live in a country where it is considered polite to knock on doors and wait until the door is opened from the inside. And no one is straightly accused of idling behind closed doors.
