I don't think this is a defining difference here. Sure, doing something by default without telling the customer seems sneaky, but its impact is small in comparison to other leaky privacy products most people use.
What I understand about the matter, the information sent is a regularly regenerated random ID and some machine information. Compare that with a Tesco's Clubcard or Walmart's Credit Card: given the information you provide them with, these companies may know what you eat, how much you spend, where you live. They can judge your income, they can project your financial situation into the future, and they probably know when you go on holiday. And I don't really think people opting in on those products really understand these implications.
I think this issue is overblown only due to it belonging in the area, where most commenters here work. As I see it, there are business practices way more harmful to privacy than this, but are happily ignored by the pop-privacy crowd just because they are convenient and have been in place for a long time.
Most of the stuff complained about in Windows 10 was already in Windows 8 (except Cortana), but "the pop-privacy crowd" has only just discovered it, apparently ;-)
