Ask HN: Why I get ads despite paying for no ads in Spotify?

I pay for ad-free Spotify. But pretty much all the podcasts there have ads. As a customer I feel lied to - I pay for no ads, but am still getting ads. Am I the only one irritated here? I guess its the content creator's decision what to do with their content and at the end of the day I am not obliged to listen, but isnt this a bit immoral? How long until we see such ads embedded in songs?
