The same way as how Massa's 'independent decision' isn't in contravention of the rule that prohibits 'team orders'.
Yeas, we all know Massa was 'told' to let Alonso past, but the rule states that such an order has to be made overtly. Which it wasn't. Which is why Ferrari have received no further censure other than a fine. For 'bringing F1 into disrepute'. Ha! Following Max Mosely?? Do me a favour…
It's a multi-million dollar sport. You think ethics really play such an important part in it all?
Massa's just not anywhere near Alonso in terms of talent. That's pretty obvious.He knows it, we all know it. Ferrari's only chance of the WC is with Alonso. Chewbacca said as much, and he should know! Why would Ferraris 'waste' all those millions of dollars just so Massa could have a race victory, when the prize they're really after is far bigger?
Massa should have made it look more convincing. He won't be getting the full support of Ferrari after today's showing. And I dare say his mechanic might be looking for a new job soon. Massa's Alonso's rear gunner, and knows it. We're talking about an Alonso who beat Chewbacca to two WCs, let's not forget.
