Sadly unable to understand half of what they were saying so I gave up after 3 minutes and found this version which seems to be at least a tiny bit better: https://www.youtube.com/watch?v=PVN13ad3UUk
For those trying out either this link or the OP link, Snowden modifies his audio settings a bit around the 5 minute mark and is much more understandable then.
Thanks, I gave up too early.
Thanks for the link. It's still hard to listen sadly. If only an official version was released.
