Dear fellow data subjects, here's a thread about a paper I just published - about how you often knowingly (or not) share your peers' data along your own, and how service providers - but you too! - benefit from this and perpetuate this unfair phenomenon (1/13) People’s decisions to use certain services may allow the data controller to know more about them, but also about others - think of a genetics firm discovering that you carry hereditary diseases, and applying this knowledge to your unaware/unconsenting family members (2/13)
