Why is it unusable for those people? Will they be held legally liable if something were to leak? Seems like Windows 10 is one of many services collecting anonymous information, what makes it different?
You can opt-out of services, if you run Windows you can't opt-out of your operating system. That's basically the line I see.
I'm fairly certain things under NDA won't go near Windows 10, even if anonymous the data is still leaked. Just like these things currently stay far away from 3rd-party services.
