Doc Searls Weblog · Zoom needs to clean up its privacy act

What they mean by that is adtech. What they’re also saying here is that Zoom is in the advertising business, and in the worst end of it: the one that lives off harvested personal data. What makes this extra creepy is that Zoom is in a position to gather plenty of personal data, some of it very intimate (for example with a shrink talking to a patient) without anyone in the conversation knowing about it. (Unless, of course, they see an ad somewhere that looks like it was informed by a private conversation on Zoom.) A person whose personal data is being shed on Zoom doesn’t know that’s happening because Zoom doesn’t tell them. There’s no red light, like the one you see when a session is being recorded. If you were in a browser instead of an app, an extension such as Privacy Badger could tell you there are trackers sniffing your ass. And, if your browser is one that cares about privacy, such as Brave, Firefox or Safari, there’s a good chance it would be blocking trackers as well. But in the Zoom app, you can’t tell if or how your personal data is being harvested.
