Got my response from the BBC regarding who is forcing them to implement content protection, as their upper-management has publicly stated, and how they came to their decisions on it. It’s pretty disappointing really.
They’ve refused my request to determine exactly who is requiring it of the BBC, on the grounds that this information is held “for the purposes of ‘journalism, art or literature'”. The 2nd part they refused generally on the grounds of it being too burdensome – my request was phrased poorly it seems. They did release one document though, though heavily redacted.
Suggestions on what, if anything, to do next would be useful.
