Has anyone ever considered the fact that since Google is often the provider of free WiFi at most Starbucks, it can secretly man-in-the-middle all of the hotspot’s traffic since it’s also a trusted SSL certificate provider? Of course, this would be relatively easy to catch (for example, by noticing that Bing’s cert is verified by Google rather than Microsoft), but the potential is still unnerving… All it would take is a few targeted, hard-to-spot interceptions to gain backdoors on many, many systems.
