No, they don't, and two seconds of searching will confirm that for you. All many of us are asking is to be able to opt out of it.
Here is how a process of enforcing looks like: https://www.reddit.com/r/Windows10/comments/3f38ed/guide_how...
It mostly doesn't apply to retail, and most of it won't work. Plus you'll disable useful functionality with no privacy implications if you follow it.
The only thing that changed since the preview build is that there are 3rd party tools to do the job for you...
The thing we now know as "telemetry" used to be opt-in, and they hide the opt-out control during initial setup behind a thing that is a link but doesn't look like one.
It can still be turned off after installation in the same exact way as the previous versions of Windows (enter "experience" in the Start menu search box), but most won't know that this control exists.
All the rest of the things causing people to freak out about privacy are related to Cortana, and the process for turning that feature set on is in-your-face opt-in, where it's clear that you're authorizing data sharing with them.
Unless you're running Enterprise or Education (both not available to single users), this is not true.
I'd imagine it'd be killable via group policy in those cases, wouldn't it?
As far as I know they give you the option to opt out of everything. Are they bad even for asking?
