I'm surely not claiming that BBC ("British Broadcasting Corporation", "a British public service broadcaster") doesn't own its content. I'm claiming they are providing their content exclusively to Facebook, a US-based advertising company, helping the said company to earn its profit from that content.

In this specific case I as a potential viewer of that content can't visit BBC's site to watch the same content, I have to watch it on Facebook, if I want to watch it at all. And I've searched for the specific video on BBC's site.

But BBC's mission isn't to make Facebook earning more money by exclusively providing to the Facebook BBC's content, helping Facebook earning more money from the internet ads tracking their viewers, and moreover, it's not why BBC is publicly funded, and why it collected its fees to produce the content: note again what I've already quoted: the "annual television licence fee which is charged to all British households, companies, and organisations" "is set by the British Government, agreed by Parliament,[14] and used to fund the BBC's radio, TV, and online services."

And it's not that BBC doesn't have its own web site.
