Earlier quoted context omitted.
BBC iPlayer is restricted to UK residents only.
It's quite sad, it's a generic "this video isn't allowed globally due to rights". That makes perfect sense when you're talking about last nights showing of Moanna, or even Eastenders (where background music in the pub might not be cleared for use outside the UK), but when it comes to a program like this you'd hope exceptions would be made.
If every impactful documentary would be given away for free, there's no incentive for anyone to pay the company behind it to make more. Journalism is expensive and I don't think enough people would donate to a large corporation through Patreon.
I would love documentaries like these to be available without restriction, but when it comes to copyright and business model, it really does come close to Moanna or Eastenders.
