"What is normality with Apple since long and apparently has been accepted by OSX users..."
As far as I know, OS X asks for permission for diagnostic data collection on first boot and can be turned off anytime. Unlike Windows, on OS X the data collected is not stored encrypted and can be inspected. They are not equivalent.
Seriously. People just irrationally hate on Apple no matter how far they'll go to trumpet user privacy from the rooftops. There is tons of objective evidence of Windows spying, yet no sources for this claim about macs. SMH.
Just having reinstalled Sierra yesterday, it does. It also asks you if you want to turn Siri on, and tells you everything Siri collects. It's also easy to turn off "Spotlight Suggestions".
Whether that's actually everything, I don't personally know. It seemed like a unnecessary and out of place dig though.
I have disabled diagnostic data collection, and LittleSnitch still finds at least 6 daemons constantly trying to do requests and send data to Apple servers.
(And yes, I also dug through the settings and disabled things in a rather counter-intuitive Spotlight menu.)
