If services are indeed doing, or moving to, end-to-end encrypted media, there's nothing the server can do here.

Doesn’t mean they can’t do anything about the noise, just that they can’t do it on the server.

The RNNoise link from the bottom of that post runs the noise suppression in real time in JavaScript. Zoom et al. could do this client side while still doing proper E2E. (Although Zoom already uses more cou that I think it needs to...)
