As podcasts do not generate profits by itself, we don't pay for it, creators rely on advertisement inside the episodes or on crowdfunding platforms.
Also news podcasts usually like to offer their sources to their listeners as a way of credibility.
In both cases the availability of links in episode's description is really important for producers and listeners.
Most of the cases the link is already written but it's not accessible not even copyable.
Deezer turning links available further contributes to enhance usability.
