If you dont already use Linux.

If at least one person tries Linux, making this post was worth it. I know im preaching to the curie here, but Linux has much better Privacy and Security than Windows or Mac. Contrary to popular belief, most apps work flawlessly on Linux and with compatibility layers like Wine and Proton, about 99% of all apps work very well on Linux. You can at least dual boot Linux if you dont want to remove your current OS. So even if an app doesn't work on Linux, you can run it on windows. A distro i would recommend is Zorin OS lite. It is very simple, elegant and very lightweight. It has all Firefox telemetry disabled by default, which is pretty nice.
