Netflix brought it out when the British media lied about what took place and what Diana said.
Really? By "brought it out" you mean that they bought repeat transmissions of a documentary that had already been made and broadcast by someone else a few years earlier? And you think they bought it because the British media lied about what was in a documentary that had already been out in the UK? This is not making sense to me.
You don't think there is just a tiny possibility that Netflix bought it to trail and cross promote Season 4 of the Crown? To maximise the revenue from their dramatisation of Diana's marital problems, affair with James Hewitt and all that... I still find it hard to believe that Harry signed up with them.
