The main thing to keep in mind is that privacy isn’t a zero sum game and that we should have a threat model. We do know that Windows is closed source and might have backdoors plus all the data collection they do and so on. This is easy to fix by using Linux and mitigates huge risks, you know?
Libre hardware is actually available but I’m not sure chapos need to go that far. At least let’s all switch to Linux first. Mint is use friendly and so is Kubuntu (Ubuntu+KDE Plasma ) which I recommend because it’s very stable, noob friendly and comes with Plasma Desktop Environment which is very powerful and easy to customize while being resource efficient. Let me know if I didn’t express my point well
