Anybody concerned about privacy can turn everything off and can also run with local account.
Which brain damages W10 back to a functionality hardly any better than W7.
And how long do you expect MS to keep that option open for you? They gave the OS away "for free" with the expectation of gathering that data on you and selling it, of getting paid to serve ads to your PC, of making money off the analytics of all that data you were supposed to send to them, of being able to funnel you to their app store for more purchases.
If they can't do that, then they can't make their money off you. How long do you expect them to tolerate that? Eliminating any or all of those "options" is just one little update away.
The noose is already tightening.
And that same 'telemetry' is backported into 7 & 8.1:
