So what does HotAudio do then? Based on everything I could observe, they implement a custom JavaScript-based decryption scheme. The audio is served in an encrypted format chunked via the MediaSource Extensions (MSE) API and then the player fetches, decrypts, and feeds each chunk to the browser’s audio engine in real time. It’s a reasonable-ish approach for a small platform. It stops casual right-clickers. It stops people opening the network tab and downloading the raw response file, only to discover it won’t play. For most users, that friction is sufficient.
The Writer is not a concrete class. Any object that implements write(), end(), and abort() can be a writer making it easy to adapt existing APIs or create specialized implementations without subclassing. There's no complex UnderlyingSink protocol with start(), write(), close(), and abort() callbacks that must coordinate through a controller whose lifecycle and state are independent of the WritableStream it is bound to.
