I'm a big Leclerc fan but I do think Verstappen deserves leniency in this situation.
He didn't get much warning and could easily have missed that flag as he was at speed.
It seemed to take far too long for yellow flags to appear in this situation.
Now, that barrier was ridiculous. Bottas should have just continued on sliding against the wall until he stopped.
Instead the Tecpro juting out stopped him very violently.
In my view there are more questions to be asked of track management then of Verstappen.
