I think the bigger issue here is that Vettel blatantly defied his team, his teammate and created a very bad PR situation (Would you like one of your drivers saying your "Vettel is protected, as usual" on stage and live tv? It's one step away from calling them a Germanic nazi regime).
He's also endangered the constructors championship, Webber will not trust any agreement made by the team anymore and will likely rather see both RB9's hit a concrete barrier than Vettel landing on the top spot from now on, and if the team take no action they're basically sending a clear message to Webber than they'll do anything to keep him from winning the Driver's Championship.
They might as well start wearing shirts saying: "We're not giving you a fair shot, feel free to deny us the Constructor's Championship, you'll find a spot with a new team in '14 anyway".
