It's pretty masterful marketing by Google really.
They've re-defined privacy to mean "hidden to everyone but google" as in, "google knows everything about me and does a really good job of keeping that information secure".
I'm very quickly becoming old and weird for clinging to the belief that no one, including google, should know anything about me other than things I explicitly tell them, and they should only use those things for purposes I explicitly permit.
Gen Y often talk about "responsible ads". Or threads about "devs need to get paid (through intrusive ad platforms)". It's... exasperating. I got a notification on my Android phone to configure topic reporting for apps a few days ago.
