I wasn't speaking to the quality of their decision making. A lot of their new UI fails to satisfy anything but the simplest of use cases but I'm sure it took a very long time and lots of meetings for it to get approved and deployed.

The Frankenstein period of old/new settings UI coexisting is further evidence of how painful ripping out OS functionality can be. I doubt anyone wanted to keep those dialogs around.

Ah, I see your point. Thank you for the clarification :)

If you look at it from their incentives (serving you adds, getting you to use their products over competitor's, etc...) then it makes sense. Uniformity and Usability appears to be a secondary concern.
