I am not an expert on that side of the industry, but I'll say that there's good reason to believe their business model is viable. People subscribe and unsubscribe from streaming services (Netflix, HBO, etc.) as they find shows they're interested in or when content they care about wanes. I've subscribed to CBS for Star Trek and canceled after the season ends. There's no reason to assume podcasting would behave differently: if there's compelling content, people will go out of their way to consume it. The trick is making audio that people will want to listen to.
