This is a much less sensationalized take on the changes. Episode numbers should be in metadata. And the policy does not say no numbers in titles, only not to put the episode number in it. I suspect that a lot of podcasts have only been putting the episode number in the title but not in metadata, which complicates presenting an organized list of episodes.
