This is where I think you’re wrong. It’s not a separate issue, because the one is part of the reason why he didn’t have all of the information. You say correct decision based on the information he had - what you’re missing in my view is that he had a role in why he did NOT have all of the relevant information. Therefore saying he made the right call with the information he had is largely irrelevant.
He didn't though. If his engineer wants to sulk and his team don't want to give him important information, that's their own issue. Andreas could very easily have come on the radio and given him the info like it or not as we see happen at Mercedes with James and Toto and then had a conversation after the race about not being a dick on the radio. His attitude on the radio was stupid and deserves a talking to, but he's not the owner of the team his principles and engineers don't have to be quiet because he asked them to. In fact his engineer shouldn't even have said 'do you want to change tyres' because that's a stupid question based on the current situation where the answer is obviously no, they should have said 'Lando the rain is going to get way worse in the next 2 laps' and then it would have been completely different.
