Sorry for asking this, but I'm not sure to understand the purpose of the locked tag. At first I thought it was to prevent platforms from indexing a feed, like <iTunes:block> tag, but that's clearly not the case. Is this tag useful in a podcast app? How is this tag supposed to prevent piracy when anyone can duplicate the feed content and remove this tag from it before publishing it to Anchor?
Sorry if all those questions have already been answered...
Did anyone take a look at Podlove work? They worked on some specs a while ago and it might be worth looking at them (especially regarding the chapters) as a lot of apps / services are already supporting them: https://podlove.org/specifications/
Intended for all stake holders of podcasting who are interested in improving the eco system
