Secure communication/networking on windows or macOS is just bad opsec.

They both have hidden certs, and non VPN activity that can be trivially correlated back to you, especially if you have OS services (can see and bypass your VPN) mixed with something like iCloud (goes over VPN).

All iDevices have a unique ID, which is hidden from apps only if you turn on tracking prevention. I don’t know the situation with Windows, I assume it’s just as bad or worse.

If I were a hacker I would be using something like a customized Sway DE and a stripped back distribo.

Also worth nothing: on macOS EVERY binary you run gets fingerprinted and sent to Apple. Again, I don’t know that Windows does this, but I’d assume it’s the same. It’s for security — probably not your security though.
