Well, at least I finally have my answer to this thread:
It would seem Microsoft Legal was here preparing for an all out attack on typosquatters to get control of their typo traffic.
DO NOT BE FOOLED BY THIS!
Getting control of Microsoft typos is not their final objective. This attack is not about getting their typos back, it's about ending domain tasting in general. It is about Microsoft getting control of all typos in the future. Microsofts desire to control the internet users experience has been well documented in the past, including lawsuits against them for unfair business practices. We all know now why they have wanted control of internet traffic...because it is valuable. They want domain tasting to end because they want a whole lot of meat available when they launch their typo software. They know that whoever controls the traffic controls the internet experience and therefor controls the revenue. They have figured out that typos make up a very large percentage of internet traffic (I'll bet almost 50%) They had their brower battle in the past (Internet Explorer) now they are going into the typo-battles. That's my theory.
