Nope, it has its reason.
After applying the Spybot Anti-Beacon suddenly bing.com and all of its services (maps, translate, image suggestions in office programs, ...) couldn't be opened in any browser nor pinged. 'General network error' or something like this.
After deep digging I finally found an outgoing firewall rule for Telemetry completely blocking the IP address of Bing.com (204.79.197.200). Don't know whether that's simply a joke or intended kick in the arse of MS — however at the expense of Windows users at least occasionally utilizing Bing services.
It is okay to block certain *.exe files with clean-cut purposes like error reporting etc. pp. when the user is told this is going to happen. It is not okay to block a complete category of services without prominent warning including a precise hint how to undo it if necessary.
