What a weird take.

How else would we have implemented this? WASM has facilitated introducing these technologies into web applications, it literally wasn’t possible before.

Thanks to emscripten it wasn’t even that hard to get rnnoise working on WASM: https://github.com/jitsi/rnnoise-wasm

I concede WASM does open the possibility of adding opaque stuff to web apps but IMHO the benefits outweigh the drawbacks at this point.
