@mona >I can remote into another machine with audio input and output bridged with low latency
I can remote into any GNU machine anywhere in the world even over a connection slower than dialup and carry out any required computing tasks via ssh.

I can even tunnel X over that ssh session for GUI things, but why would I want to do that?

Meanwhile good luck getting RDP to work over even high-speed 56k dial-up.

>a feature that's been available on macos and windows for years
Taking a gamble I reckon GNU/Linux had that feature before macos and windows did, via VNC.

There is free software that does such sort of remote desktop feature; https://remmina.org/ and supports all the protocols; RDP, VNC, SPICE, ssh+X etc

To get audio input and output bridged, you'll need to have systemd/Linux with pulseaudio installed, but of course you'll love that.

But of course you won't come to freedom - you'll continue surrendering your freedom to microsoft no matter what.
