I don't disagree with what you're saying (that people don't always understand the implications of their casual dealings with big evil corps).
But can I offer another perspective, one of potential differences in values?
Privacy, for me, isn't a super high concern. Having some is nice, but it's never my top consideration. (I know this skews against the dominant HN sentiment, and Slashdot's too before it. That's okay.)
Science, however, IS huge for me -- even when the science is done by sub-optimal orgs like your Big Evil Corp du jour. When I learned that Google owned 23andme, my reaction wasn't one of horror.
Instead, it was "Oh cool! Maybe they'll actually have the resources to correlate this with all their other data on me." I then proceeded to sign up for Google Health, Google Fit, etc., and made sure to upload my health readings to their servers in the explicit hope that they would be able to merge it with 23andme and other data. My dream was that one day they would be able to identify genetic markers not just for health and lifestyle stuff but also behavioral data, like my YouTube preferences and Gmail conservational styles.
Gattaca to me was a utopia, not a dystopia.
I know that's probably not a common viewpoint. But I was really excited by the possibilities, and it doesn't bother me in the least that Google knows so much about me. I just wish they'd do something useful with all of it.
FWIW, I just asked my partner about the data sharing. She said she's fine with it and would opt-in if given the choice. Most of her family too (many were early adopters of genetic testing). One individual in particular skews conservative and is conspiracy-theory-prone and would probably not, though.
I wonder how much of this preference is political or personality or similar. Would be interesting to plot privacy needs vs the Big 5 personality test, maybe. But how would you get participants? Lol.
> It's clear that they wanted the data, not clear that there would be benefits to the participants, the data returned is just too coarse for that and akin to doing a lot of screening without symptoms, a practice that the medical profession has warned against repeatedly.
To this point, yes, you're probably right, but these things are rarely black and white. It's a false dichotomy. They can be harvesting all my data but STILL offer a useful service at a good value to me. And -- more importantly -- nobody else stepped up to offer the same thing with a better business model. Whether it's 23andme or YouTube, it's not necessarily the case that all their customers have their blindfolds on. Some of us are just OK with the tradeoffs and buy into it willingly. The medical profession isn't always able to meet consumer desires, to say the least. And even if 23andme didn't do it perfectly... at least they did it. If the medical profession or the government wants to offer something similar, I'd still be interested... they just haven't yet, AFAIK.
