Chrome doesn't auto-update on Linux, nor presumably in other platforms with working package managers. Windows software is expected to update itself or ask the user to do it, so Google took the approach that was easiest for non-technical users, which IMO is much better for their security. When users are running an old, unpatched version of a browser, you don't need very advanced tactics to pwn their machines... And for what is worth, there must be a way to disable Chrome automatic updates, because the PortableApps version of it doesn't (or didn't, a while ago) auto-update.
