Raikkonnen should not have been there, he had nothing to do in that position when he obviously saw that there is no enough space for him. He is at fault becaause he was desperate to be exactly there. And Fernando had the choice where to go because obviously he was the first passing through this exact part of the circuit and Kimi just tried to follow him.
Err, he was there before Fernando pushed him out, there WAS room until Fernando came there, he wasn't behind Alonso (meaning completely behind, they were rear wheel to front wheel), and he left all the room there was to leave, but Alonso decided to push him out from track regardless, just look the video you linked when it's from Massas perspective.
