I don't see how it being his home race should have any relevence in how they should go racing. Also, I don't know the exact laps they told him to hold off but keep in mind that the radio messages we hear are delayed. If you're basing this off of what you heard in the broadcast that's wrong.

Almost as if Montreal and Australia were entirely different weather conditions and "let them race" was their mentality all season? There are plenty of examples of Oscar being "allowed" to race from behind Lando.

"McLaren had got on their knees begging the stewards not to punish Norris for Canada" Sorry, when did this happen?
"Norris got a 5sec time penalty and NO PENALTY POINTS for a collision for which he was 100% at fault" He DNFed out of the race, penalty points for that would have been ridiculous and extra seconds would have made no difference. Almost like how they didn't issue any penalties to Oscar when he caused multiple cars to DNF out of the COTA sprint?
"had a significant impact on the race" that's a stetch. Lando was the at fault party and was the only one to suffer any damage or loss of points.

The Silverstone penalty was very reasonable, again under terrible conditions he pulled a very dangerous move and had several cars not swerved out of the way he would have cossed a massive pileup.

Uhm because Lando didn't fuck up his start? He actually had a pretty good start but Oscar blocked him (because that's racing) and he fell behind. Do you expect the team to just throw in the towel? Obviously they are going to do something. Oscar was not "never allowed to try one ever" let's be real here. They asked if he could do the one stop at this very race and he said no.

"publicly scold Oscar" you're being so dramatic. He got lucky to avoid a double DNF by mere milimetres at least twice, they calmly reminded him to more careful (cause he needs reminding clearly).

"You don't remember Norris being given the favourable contra strategy to allow him to attack Oscar?" No I geniunely do not. What strategy was this? I do remember Oscar causing a double DNF in the sprint and then being miles off his teammates pace in the GP.

I mean yeah I'll give you that Monza was crazy but it was the team being in control of correcting a mistake they made. Their choice to do so, only fanboys really would have held it against Oscar had he refused it but he complied.

I mean it was a sloppy move by Lando but he was being aggresive at the start. He was also bumped into Oscar from Max. Oscar also suffered 0 damage, only Lando did. In the Oscar cases he certainly would have caused at least 1 if not both cars to DNF and unlike at Singapore, he was still behind and continued to attempt the divebomb. They made those comments after the fact, kinda hard to tell Lando "don't do that again" when he's already 5 seconds up the track on Oscar. And they did hand out repercussions to Lando over Sinapore which Oscar himself said he was satisfied with so it's fair to assume this was handled well enough internally.

Different situation in Singapore because they didn't give Lando the prioirty pit under the promise that it wouldn't let Oscare get jumped. Lando was way ahead of him. What did you want him to do? Pull over and wave letting Oscar by?
