French public broadcasters are ad-supported, they don't have to separate local and overseas websites/apps/revenue logic. I've seen another comment about the BBC having ads for other BBC content; I already get ads in my Radio France podcasts (just the one before the proper content), and they're dynamic, so they surely change them depending on where you listening to maximize revenue. Probably the same type of dynamic advertising I get when listening to US podcasts with inverted French-speaking ads.
