Bottas should have been aware of the possibility given where he was on track and clearly did not look. I call that a racing incident at worst, and Bottas' fault at best.
It was a very late move.
Bottas took the racing line and had no time to react to Raikkonen throwing it into the apex.
Even if Bottas gave the space, Raikkonen would have straight lined the corner straight into Bottas.
