> Also, currently, Windows even AFAIK sends keystrokes to the US,

This is exactly the kind of FUD I'm pushing back against. You just casually mention this like it's some established fact. Do you have any proof of this?

Surely it would be extremely easy to verify, given that anyone can set up a Windows 10/11 VM with mitmproxy and see every outgoing connection. I myself have quite a number of those VMs for various application-related RE projects, and let me tell you, I've never noticed every single one of my outgoing keystrokes present in the logs.

You'd think it might stand out...
