I worded that rather provocatively, but Google chrome is the man in the middle between you and the servers. Since it manages TLS connections, it could access everything if it wanted to. I am not sure it does send detailed telemetry on visited pages and contents to Google, but that wouldn't surprise me (and your sibling comment hints at that).

I wondered if there was some correlation between Google pushing for HTTPS and their introduction of chrome, but I guess that's unrelated, as they didn't have this capability before (except for users of their toolbar).
