Anyone new to these tools will be horrified at how aggressively Windows tries to violate your privacy with unnecessary data collection, phone-homes, remote calls, etc.

Linux is galaxies better in that regard. I still don't want anything making any connections without my explicit knowledge and consent though, and there are lots of packages and applications that try to unnecessarily exfiltrate data without asking. If you aren't using an active firewall, you are leaking.
