As a proud listener, viewer and supporter of the BBC, this is one part that seems really unfortunate. Why should I need an account to listen to BBC content? All the pages on the BBC website that pretend to answer this question are evasive and dodge the question. What do you have to hide?
Please re-consider. Allow your content to be made available via open standards, like some of your podcasts. Let us choose how to consume the content that we fund.
Please let me use whatever device and app I want. I don't use a Google account on my android phone because I value my privacy. That means I can't install the Sounds app. Please let me listen to the BBC without having to have a Google or Apple account.
Please let us listen to radio without being tracked. Trust is already eroded given the evasive wording on your help pages.
Please think of those people in the UK who don't have a post-code (like visitors) or email address (like the elderly).
And please come clean about why you need personal details to listen to the radio.
