I find it a bit disturbing that M$ doesn't look into the law a little before sending out the standard "we will sue you for all your worth and a bit more template" mail. I think he should get some $ in compensation for the threats.
On the other hand of him sudently being an expert in the subject cause M$ gave up the hunt for a useless domain that is pro M$ is bs. Who in their right mind pay that much money to subscribe to a newsletter from a complete stranger just to see a responce letter from M$?
