I paid for a service that gave me useful insights into my ancestry and health profile, and it cost me less than 30 minutes with a teledoc and a basic blood test. I opted out of keeping my sample in storage and using the data for research at the time, and deleted my account and data a few months ago as a matter of general digital hygiene, but even if they didn't honor any of that, I don't see why I should be concerned about it being out there. The privacy concerns were quite obvious and oft-discussed several years ago when I sent my sample in, so I certainly didn't get "bamboozled". I'm sure there are many people who didn't consider that their data may not be private, but how many actually care about that?
