This is correct; the Spotify embedded player - which the foundation has mistakenly used here, uses a DRM technology called Widevine.

There are other, more sensible, tools to use here: not least, the HTML5 "AUDIO" tag, rather than a proprietary embedded player!

Link is broken. Remove the trailing // to fix it. And the podcasts work for me - how can I check if they're using DRM?

Usually an desktop browser shows an symbol if drm is used.
