There are also plenty of audio productions which cost money but which would otherwise clearly be identified as "podcasts" if they were free and listed on podcast directories. The Howard Stern Show, for instance.
So I think the issue here is clearly just about the semantics of the term "podcast" and how people apparently strongly identify the term with free audio content available on multiple platforms. Presumably people wouldn't be too upset with Apple hiring Howard Stern to do a video interview series distributed on its premium video streaming platform. But apparently people would be upset if Apple hired Howard Stern to do an audio interview series distributed on its so-called "Podcasts" app.
