Not sure what Linux has to do with my comment. Are you assuming I use a Linux "distribution"? Sometimes I have done so, but only occasionally when I need to check something on Linux. Anyway, I am missing your point.
Well, I simply highlighted the difference between theory and practice. The average user does not have the money to audit open source software. And even if you get someone to bankroll the cash, you will need to re-do the audit for every single check-in since the audit. You made a point about Windows being impossible to audit, but in practice you're in pretty much the same boat when it comes to Linux.
And then there's this mythical "average user". But what does that have to do with me and my own solutions?
I know only one user: myself. I know what works for me. I live in a tty. Do I need a Windows GUI? No.
Finally, I also know that what one can do, another can do. But that is their decision and I am not trying to convince anyone to do what I do.
Windows is a massive, complex truckload of legacy source code that keeps growing with every edition; it has a lot of flaws and the number grows every year; it is not "open source" in the sense of public source code respositories and enabling users to compile from source. This is not opinion. It's fact. These facts do contribute to the state of Windows "security". Bravo for fixing flaws in recent years. But no points for having them to begin with: poor quality control.
