@Kristian Walsh: part of testing the software is seeing what data it's collecting on you, how you have the ability to turn that off and how much of what gets turned on when you tweak the various knobs.
I have absolutely no problem with Microsoft collecting info on my beta copy. I signed up, I know how that works. I even logged in with my Microsoft account in order to leave feedback.
But when I go explicitly hunting to turn it all off in a separate, created for the purpose of testing that functionality, VM I should be able to do it. Ensuring privacy controls work is a critical part of ensuring that the operating system is ready for prime time. And, to me, it's far more important than making sure the graphics subsystem works, or that the Start Menu doesn't irritate me too much.
I'm beta testing the product and there are notable bugs in how it handles privacy. I'm willing to bet Microsoft won't address them unless lawsuits are involved. Quite simply because that's what it always seems to take with them to get privacy taken seriously.
So you'll have to excuse me if I make my fuss now, in beta, before the product goes out. That way at least there's a paper trail that says "no, actually, this was raised with you repeatedly."
All part of the process of holding their feet to the fire. (Well, bitching on El Reg's forums is an irrelevant part of that compared to sending formal feedback through the various other channels available, but damn it, it makes me feel better.)
