At 0:56, Arnoux did the same as Ricciardo, had the same result with both cars continuing and no one complained.
Just to nitpick, but the situations are not similar at all, as Ricciardo is behind, and eases slowly up so his front wheel pushes Raikkonen out wide by punting his rear wheel.
In the fight you link to, Arnoux is in front, then they are side by side, and properly side by side as well, out of the right hander, stays side by side in to the left hander, and when there is contact, Arnoux is having his left wheels on the white lines. The two are as comparable as dinner before, and after you've eaten it...
