Microsoft is stepping up its anti-Google campaign, in a couple new moves clearly intended to generate FUD (fear, uncertainty and doubt) about its rival's products, corporate image and credibility. In the past two days, Microsoft launched at least two separate offenses: one against Google Apps, which competes with Microsoft's key businesses -- productivity software -- and the other an attempt to capitalize on the news surrounding Google's apparent circumvention of Safari privacy controls. Google must defend against attacks from Microsoft on multiple fronts -- they're opportunistic and follow a pattern of attempting to cash in when Google is vulnerable. It also happens with increasing frequency. Consider Microsoft's attempts a year ago to justify copying Google results by turning around and accusing the Mountain View, Calif. company of click fraud. Then there was the time Microsoft hid behind a group working for "fairer search" to accuse Google of unfair competition. But that's the past.
