Beware though that "available on Spotify" (idk Podimo) doesn't necessarily mean that it's exclusive there. But it's very common around here and many people use it for convenience (and the podcasts can advertise it as "look we are in this fancy mainstream app", not weird (?) RSS, while they likely offer that too). I myself used Spotify for freely available podcasts too, only recently switched to Podcast Addict for nerdy automatic download settings
