I take issue with the term "fake podcast." This is like calling AI generated art "fake art."
The issue they have is with low-quality content. If the AI generated content was better than most human-created podcasts and were making their engagement numbers go up, I doubt they would be calling them fake or removing them.
It's fake art made by pouring a bunch of images into an algorithmic hopper and spitting out something vaguely like them without paying a single cent to anyone whose data was grabbed for this abuse of fair use, at a huge cost of power hidden away from the user.
