Official news (with citation) is what we like to see.
All of the people who bought tickets to the theater and the cinema got to see the entire thing. It was great to be able to see even part of the event live-streamed and for arte to make it available for the next few months on demand, and while I would rather have seen the Guillem/Le Riche pas, thinking about it in the cold light of day, if it was important enough to Le Riche for her to appear, he was willing to meet her conditions, and management agreed to the whole thing, then I don't see what the problem is.
The entire Richard Strauss concert from Dresden, for example, isn't available online, either. Several parts went unaired (and the announcer talked over some of the orchestral intros...)
