Obsolete topic?

Everyone and their (agile) grandmother have now been ranting against Microsoft article on Guidelines for Test-Driven Development. I was in Benelux and Germany these last days and missed the "happening --" I just got recollections of it (mostly from Ron, Jim and Mike). Eventually, I went to Microsoft's website to read the despised article. To my intrigued interest, it has been removed, and replaced by the following mention.

Guidelines for Test-Driven Development
This topic is obsolete and has been removed from the MSDN documentation.

Now, I know what it is supposed to mean, but I find it funny (as in strange) that Microsoft ends up declaring that TDD is an obsolete topic...
