Microsoft can declare what they want. I praise it for it's LACK of back door call home abilities. Data gathering of user behavior is happening all the time and is made easier with each new browser, at least with IE6 I am/was able to efficiently block this undesired behavior.
Of course it means I'll have to keep my copy on a disk along with windows xp (or earlier) and wipe every new hard drive I get before being able to use it but hey...
China currently leads the rankings in use of IE6, with around a quarter of internet denizens still firing up the browser
In a country where censorship is the norm and access is strictly enforced it's a popular browser for a reason.
