But you don’t. Because you don’t
Exactly, that’s the point he was trying to make.
You can’t harden windows to the point of an acceptable level of security. That is the inherent nature of proprietary software.
Prove to me that your windows system is actually “hardened” and that you have no backdoors or telemetry broadcasting at all. At the very least, Microsoft still knows what you are doing, you cannot trust your 3rd party firewall because windows can still sidestep it.
I don’t even know who the fuck those people are, all I can tell you is that there is a reason that any professional application that requires legitimate security, runs on foss systems, or at the very least source available. If you are too stupid to realize that, then you really don’t have any say in this matter whatsoever. It doesn’t even just include baremetal Linux either.
I don’t know who you’ve been arguing with on this, but I actually make a living working on Linux machines, I’m not even coming at you from a freetard perspective, solely work experience.
