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".

Worst part is, they've pulled that stunt with "security" before. Confidentiality is one of three core principles of information security. Privacy is that applied for personal information. Logically, privacy is an important field underneath information security.

But thanks to Google's messaging, you've got infosec folks saying shit like Chrome being the most secure browser. Its sync isn't even end-to-end-encrypted by default, because Google would rather not close off access to your data. You could only consider Chrome secure, if you're ignoring Google as an attacker.
