He did not stoled anything, Massa was not title contender, he gets paid by Ferrari and would be stupid not to do it, same as Kovalainen in Germany 2008.
You can't judge same situations with different criteria because of your interests... is like if get mad because tomorrow Vettel gives position to Webber in case that means Webber wins instead of Alonso... probably somebody will expect Red Bull to suicide but certanly not me or Emanuele Pirro, the italian marshall for this race that said Red Bull would be "dumb" if they don't use team orders in case they need them to make one of their drivers win... but oh wait, he's italian mafioso
