Vettel's penalty in Canada too was stupid and still it was awarded because that's what's written in the rulebook.
Today, if it turns out to be a penalty, it won't be any different. A stupid penalty, but one that is against of what's written in the rulebook and as such, "rioting" now will be as pointless as it was in Canada.
Last year Vettel impeded Sainz in Q1 and despite Sainz already qualified (thus he didn't really need the lap he ruined), he still got penalized for it.
Yesterday, Hamilton impeded Raikkonen in Q1, same track, different corner, and the too was penalized because that's what's written in the rulebook.
Instead of crying (pro-Leclerc or pro-Verstappen, it's all the same), the "negativity" should be aimed at the rulebook, not at the stewards for applying what's written in it. If they change the rules, these stupid penalties will go away. But if they don't change the rules, this endless moaning on social media and otherwise will always and forever be meaningless as it's not really their fault for applying the rules.
"Fans" often accused them of being inconsistent for well over a decade at the very least. For once that they finally actually act consistently across different races with different stewards, people still find a reason to verbally harass and threaten them.
It was a good race, Verstappen won on merit but made a dumb overtake taking a risk he didn't need to. With the pace he had, he could've passed Leclerc in the pitlane and still win the race by a margin. But with 2 or 3 laps to go, especially at that age, he's still too immature to think straight and stay focused on more than just the short-term benefit of things. He had all the time in the world, but he wanted to do it as soon as possible. That's the mistake he will probably pay for if they penalize him.
But if they don't give him a penalty (that should be there according to the rulebook), it will set a really really really bad precedent, considering how controversial things got in Canada as recently as 4 weeks ago.
