Indeed, though the key word in your interpretation is "might".
Bottom line is that it was a racing incident. Sure, if Seb hadn't try to squeeze Max the incident may not have happened, though that's the same as saying if Max had braked it would also have been avoided. What Seb did was try to protect his position by moving once across the circuit, a move that may seem to be quite hard however he's fully entitled to do so. He hasn't been let off the hook because he was never on it, Ferrari driver or otherwise.
