I trust Microsoft with my personal data more than I would FaceBook, Google, or Equifax. Microsoft's core business is selling software and services, and whatever data selling or sharing they do is just a marginal side hustle. In contrast, the other companies mentioned are pure data brokers. Yes, FaceBook, Google, and Equifax have applications and even consumer product oriented lines of business, but if you look closely they are all carefully engineered to expand the surface area of data they collect about their customers. They have to hoard data in order to survive, and I don't trust desperate people or organizations that feel threatened.
