Because they're not actually doing that?

These researchers did everything they could think of to come up with the most concerning headline.

I imagine someone, somewhere is going to make a video conferencing app that closes the audio interface every time you press mute. I also expect few people will use that option because it adds additional latency every time you unmute.

I want my mute button to work ASAP and I don't believe Zoom (or anyone else) is interested in whether or not I'm eating while muted.
