I get the impression they would rather you listened via them then broadcast.
Yeah it’s a bit annoying how BBC keeps mentioning their digital services. They want you to have their content and they want to track you. But I think their top priority is just that you tune in one way or another. Offgriders give them the advantage of undivided attention. They don’t have to compete very hard for the attention of those without Internet.
OTOH, BBC is a special case because they get nothing from broadcast ads. I don’t even know how they are funded. Sure they get tax funded in the UK, but what’s their incentive to broadcast in continental Europe which apparently does not fund them?
(edit) a lot of FM and DAB stations have no digital resources that would track you (extremely basic websites without even a schedule). Some stations seem to have no web presence at all. So in those cases it would be interesting for them to emphasise their privacy alignment.
Not quite sure what you mean. What are numbers stations? Do you mean FM where the frequency is a memorable number?
