Long article which you should read but here are some choice sections, definately gives the impression that RBR is Vettel's team.
Last year after the race at the Nurburgring, I went into the Red Bull motorhome to congratulate Mark Webber on his first Formula 1 victory.
There was no sign of Webber, but team principal Christian Horner and Dr Helmut Marko were deep in conversation next to the bar. Both looked pretty serious. Webber had won the race while Vettel had finished second, largely due to being rather tentative in qualifying, where he ended up fourth. I watched him very closely that weekend and spoke to him several times and I felt that he was really feeling the pressure of a home Grand Prix where you are expected to win.
Mark Webbers partner Ann Neil came out of the drivers area and walked across the room. One of the team said something like, Isnt it fantastic, Marks win? To which she replied rather tartly, Im glad someone around here is pleased. And indeed it did seem more like a wake than a celebration.

But there was a suspicion tonight that in the laps leading up to their collision on lap 40, Vettel may have been given more favourable conditions than Webber and may have had more engine revs at his disposal. And it may have been because he was under threat from Hamilton.
In the situation Sebastian was in, he had no other choice than to act the way he did, said Marko on F1.com. We informed Mark about the situation and it is for the driver to decide. The fact is that if Sebastian hadnt passed he would have been overtaken by Hamilton. Unfortunately, Mark was not told about the situation accurately by his race engineer.
