This is surprising -- I know! -- but competing companies sometimes advertise against each other. Microsoft have been doing this for quite a while (see Gmail man [1]) and they seem to think that the privacy aspect is enough of a weakness in the Google armor that it's an effective campaign. So far I don't think Microsoft have had as many problems on the privacy front as Google or Facebook so this is probably not a rash decision on their part.
