On Sky Sports Italy the shown the same case in the same track between Alonso (in Verstappen location ) and Vetten (Hamilton) happened in 2010 ish.
Alonso didn't close the turn and let Vettel pass otherwise was a collusion.
We can even look at the situation later in Sunday's race, where Hamilton overtook Leclerc to take the lead in the closing laps. It was almost a perfect copy of the position on lap 1, at the same corner, Hamilton coming up on the inside... and Leclerc left room for him by taking a wider line. It's what most drivers would do.
