Rock Health buries the lead -- consumers don't want to share with tech firms. [Rant on.] Digital health firms are having a tough time, despite upwards of $6 billion from me-too investors, and that's just last year. The Rock Health Digital Health Consumer Adoption Survey 2015 of 4017 people is a testimonial to the mismatch between investor optimism and consumer skepticism. On the skepticism front, blame is placed on a variety of factors, including lack of sharing of data across health providers ('Tech companies don't have the problem, it's the siloed health institutions.') But wait. "The contenders–Apple, Google, Facebook, Microsoft, and Samsung—all fared poorly, with approximately 5 percent of people saying they’d share with these companies. Facebook was the outlier -- only 2% would share health or DNA data with the social network." Duh. Despite a few hysterically enthusiastic reads of this data, like Forbes, a few saw gloom. Kudos to MIT Technology Review and a few others for noting the tech company chart, small and at the end of the report.
