Very interesting article about the state of Linux security.

While I agree with what it says, I don't agree that Windows is going in the right direction, because the mitigations that windows introduces are useless as long as they don't break backward compatibility.

Windows has a basic problem, an architecture problem mainly due to the binary backward compatibility which makes security problems dragging and difficult to fix.

On the other hand, if you need extreme security and privacy, use Qubes OS.
