RBR is interesting because it is privately owned and one of the owners is also the major sponsor. This does make them a lot like Ferrari, so being 'Kimi-ed' due to the whim of the owner is possible.
However, although they have done some really stupid things, I can't believe the 'team' would take steps to further reduce their chances of winning one or both of the 2010 championships. Therefore, helping both Mark and Seb get the best points finishes will be the sensible thing to do.
However, next year is a different matter. I wonder if they have it in their power to move Mark to Torro Rosso without breaking terms of contracts?
This would be the worst of all worlds for Webber!
