I have already switched to Firefox and loving it (Facebook container, tracking protection enabled), but these changes are welcome and responsive. I hope this is a wake up call that privacy implications need to be seriously considered during product design (even if the intent was better UX), and hidden changes without any UI/notice is going to make issues blow up far more than if there was clear in-app communication.
Maybe am too cynical, but I think it would be a wake up call to hide such features better in the future. This is Google we're talking about here.
