I use it extensively in my OSS work (https://github.com/mickael-kerjean/filestash) mostly around:
1. creating plugins that get executed in the browser to render files like Parquet, PSD, TIFF, SQLite, EPS, ZIP, TGZ, GIS related files and many more, where C libraries are almost always the reference implementations. There are almost a hundred supported file formats, most of which are supported through WASM
2. creating plugins that get executed in the server to generate your own endpoint or middleware while being sure you can't start exfiltrating data (which can be other people's files, and other sensitive stuff)
3. in the workflow engine to enable people to run their own sandboxed scripts without giving those a blank check to go crazy
It also simply lets you use rust on the web. That's why I use wasm. It's actually an extremely nice experience. I write all my business logic in rust, and all my UI logic in javascript. There is rust tooling that automatically generates typescript types and APIs for you that make interoperating the two languages basically effortless. And by using rust/wasm, I can reach a level of performance that would be hilariously impossible in javascript
