Yes - the BBC, ITV and C4 will want metrics on who is watching and what they are watching to drive personalisation.
As seen with the BBC's decision today to pull their radio stations from the TuneIn app from the end of August due to TuneIn not agreeing to share data metrics with the BBC.
And not at all to drive people to the BBC Sounds App, which I really don't know why it exists.
In an 'all IP' future - which is where broadcasting is going, personalisation and recommendations will be key, and gathering metrics personal to each user are vital. They are already a major aspect of Netflix's and YouTube's success (and why Netflix has user profiles within its app).
Additionally, once (or if) RAJAR and BARB become increasingly irrelevant, the BBC needs listener and viewer metrics to understand what viewers are watching and listening to and like or don't like.
Increasingly, any platform that can't supply the BBC with the metrics it feels it needs, will not be able to syndicate the BBC's content. The BBC has been quite audience-friendly with the TuneIn move. They will continue to supply TuneIn with BBC content on platforms that only support TuneIn asa route to accessing BBC services (like Sonos), but other devices (Amazon Echo, Google Assistant etc.) where BBC content is available via other routes that provide the BBC with audience metrics will no longer have TuneIn support for BBC services (as TuneIn don't provide the BBC with the data they want, in return for access to BBC services)
The BBC Sounds app, like the BBC iPlayer app, is a way of ensuring the BBC gets the metrics it wants, and is a way of developing a personalisation profile (like Facebook+Instagram, Twitter, Netflix, Amazon, YouTube+Google do) that will increasingly be vital.
