In terms of security, every OS Is vulnerable- some (obviously) more than others.
Sure, Windows Is renowned for It's Insecurities and data collection (namely Windows 10), but It largely depends on one's usability and overall configuration. I'm on the Windows platform and bullet-proofed It's weaknesses and tracking.
And those who perform Windows Updates, stop. Are you comfortable with Microsoft messing around with your OS? Are you aware of "exactly" what's being Installed and derived from your system?
Enough said.
