When it comes to tech, companies, investors and entrepreneurs mostly talk about what it can do instead of what it should do. For example, should health and wellness apps funnel detailed personal information about their users directly to Facebook without people knowing or giving permission? The Wall Street Journal reported that on Friday, and it's only the most recent example of tech companies doing something that makes you think, "Didn't anyone ever ask if this might be a bad idea?" Caterina Fake is the co-founder of Flickr, a venture capitalist and host of the new podcast "Should This Exist?" She told Marketplace Tech host Molly Wood that investors are slowly starting to ask those questions. Today's show is sponsored by WellFrame and Lenovo for Small Business.
