Matthew Green has this excellent bit in his article about Chrome’s auto-login bullshit:
This pattern of behavior by tech companies is so routine that we take it for granted. Let’s call it “pulling a Facebook” in honor of the many times that Facebook has “accidentally” relaxed the privacy settings for user profile data, and then—following a bout of bad press coverage—apologized and quietly reversed course. A key feature of these episodes is that management rarely takes the blame: It’s usually laid at the feet of some anonymous engineer moving fast and breaking things. Maybe it’s just a coincidence that these changes consistently err in the direction of increasing “user engagement” and never make your experience more private.
