Re: About-face
I never had a problem with being tracked in the technical preview. I had - and have - problems with the inability to turn this stuff off, or even to know what is tracking me and why. And for all the reasons that were explained in the article...and in the subsequent posts to the very thread you linked.
I do, however, find it curious you left out the conversation that starts here, however, as it is closely related and relevant as a progression of the dialogue.
I strongly encourage anyone interested to read both threads in their totality. Good points were raised by a number of people.
