Yeah, if someone e.g. gets my complete hw fingerprint, I'm identifiable. But it's no worse than I'm already uniquely id'd by visiting pretty much any website today. I don't like it, but I also don't see a point in being outraged when my music player does it but not when my favorite website does it.
Well if you make a piece of useful software I'll install it (I'd rather install it myself).
I'm not very generous with my data at all - but I'd rather trust my firewall to protect my data, than a dialog that asks me if I'm OK with sharing it. That was my point.
