Bottom line though....Windows 10 is also opt-in.
In regards to being able to change privacy settings or in not having to use the OS?
Either way, you're wrong. Even after locking down the privacy settings, Windows 10 is still sending personally identifiable information back to Microsoft's servers.
And using Windows is not optional for many people; many modern applications require Windows (applications which many people may have to use for work or school), and most pc's are sold with it already installed (especially on the affordable end of the spectrum). In the year 2015, access to a modern and up to date pc is no longer optional. You can't even apply for most jobs without a pc and internet access. You sign up for free email, social networks, or whatever other services, sure you can expect to be tracked. These services are not necessary, and there are typically competing services which will behave better. But simply logging into a modern OS should not be the point at which you're signing away the rights to your data, especially when you realistically often have no other choice.
I suppose, technically, you could consider it opt-in, in that you could write your own OS, or maybe go live in a remote cabin in the woods. But I was trying to stay more within the realm of realistic here.
