FM radio using the 3.5mm jack has nothing to do with the jack itself. You could make a USB-C to 3.5mm jack that does FM radio reception too… or any long cord. The reality is nobody (comparatively) wants FM radio anymore. They barely did when it was released. With widespread data plans you can just stream it via the internet, it’s more convenient, it sounds better, and reception isn’t an issue indoors or in bad signal areas.
