Google tracks link clicks in Hangouts

Open a Hangouts chat from the GMail web client. Send a URL to someone (or receive one). Right-click → Inspect Element; the actual link will be a redirect through google.com.

I can't be the only one who thinks Google is severely violating user trust by tracking clicks in supposedly private conversations. (I know Facebook does this too, but I don't think anyone would be surprised at Facebook's behavior.)
