-Of the 40.8K Libsyn-domain feeds in Apple Podcasts, more than half have their website properly set to something other than a Libsyn domain. Leaving 18.3K Libsyn-domain feeds pointing to Libsyn-domain websites. But without visiting every web page, that remaining number could contain any split between intentional an accident.
-SoundCloud has 83.3K domain feeds in Apple Podcast, and a smaller-than-I-expected-but-still-big 48.8K of those feeds have a Sound Cloud URL as the website.
-Anchor has 72,169 feeds in AP. All but 3 are pointing back to the podcast’s Anchor webpage and are not a podcast’s own branded website! (Edited by Request DJL)
