Nests Tony Fadell recently addressed one of the biggest issues surrounding Googles $3.2 billion purchase of the company: privacy. At the DLD Conference in Munich, Fadell stated that any alterations to Nests privacy policy in the future would be opt-in, and the company would be transparent about those changes to its users. While Fadell says there are no planned changes to Nests privacy policy yet, hes not ruling the idea out entirely. Google is no stranger to changing its privacy policies, and Fadell seems to realize that the acquisition could eventually bring changes to Nest, even if they are not immediate.
