Are there some entities that don’t want their Apple Podcasts to be transcribed?

A couple of weeks ago, Apple Podcasts was announcing that podcasts transcripts were now available. I checked at the time and it was indeed there for all my podcasts delivered in English. Last week, I realised that transcripts are no longer available for some of the podcast such as bbc global news, bbc Sacked in the morning, OTB, RTE news at one. I upgraded my iOS to 17.5 but to no avail.

Does anybody know what is going on? Have these entities decided they don’t want their podcast to be transcribed? I’m asking because some other English podcast still get the AI generated transcription
