Why does one choice of default "destroy intent," while the other doesn't? Why do you assume the default setting of allowing tracking is the correct one?
Microsoft don't sound like the problem.
A browser should protect my privacy, give me tools to filter out content (images, ads, off site material), protect my browsing history, etc...
This is all besides the point - when every browser sends a flag that states "Do Not Track" - then "Do Not Track" loses all meaning.
Its not a matter of "correct", its a matter of what people bought into when the initially decided to support DNT.
