Chrome updates are non-disruptive (e.g., doesn't bug you to restart your machine every 15 minutes) and automatic.
It's a far cry from "you have 7 critical updates that require your attention", or "your computer will automatically shut down in 3 minutes to update unless you click this button that extends this by another hour".
Or if we're talking about Adobe: "looks like there's another 0-day massive security hole, Flash player needs you to drop everything, shut off everything with a web frame so we can fix this".
Or to balance it out a bit Apple-style: "your browser, Safari, needs an update. We will inexplicably need you to stop whatever you're doing and reboot to update your browser"
So yeah, "never needs upgrades" isn't technically correct, but it's pretty close to it.
