I think this is armchair expert nonsense.
For the video and pushing: The rules are different now. As seen with Lec, if they push on this location, they get a penalty. And Max would not have gone into the gravel without carnage, most probably Pia would have just ruined his own race against Nor by destroying his wing.
For defending: Pia was committed on the inside line. There was no space to move over more than he did. He moved to the maximum he could move under braking. Leaving the inside open would most probably end in both Rus and Ver passing him...or Nor. Standing on the inside was the chance for P1 and secured in the end P2. Could have been much worse on the outside with maybe even gravel.
What were the issues:
- Bad start with a lot of wheelspin in 2nd gear. Same for Ver.
- Too early on the brake. He did not want to cause big carnage there. In the end this is what allowed Ver to pass. Not the line, not aggressiveness against Ver.
