Mclaren are disgusting. Their treatment of a driver who has literally been withe them since he was 17. Who stuck with them, who grafted for them, who was loyal, who was kind, who was the driver some teams wish for...
It's not just their lack of morals and lack of shame but they still expect him to be good to them. He gives and he gives and they take and take and that's how they like it. That's where they want him.
They don't want him to race they don't want him to win (see their reaction in Australia - or lack of from Stella as he didn't even bother to turn up - and the sprint race in Miami). They have already rigged the championship: they have built the car around Oscar (even thought it actually makes the Mclaren's performance worse and more unstable), they praise Oscar and contiunally contribute to the (entirely false) PR ploy by him and his Personal team rooted in ableism and toxic masculinity - that completely undermines their other driver who has spent his whole career speaking out about and advocating for MH struggles. They then completely ignore the abhorrent and frankly disgusting abuse/threats that that driver gets from fans/media and actually contribute to this by either not responding,blocking the fans that are trying to get justice or respond in favour to the perpetrator (see Alan Jones). Not helped by the PRstri effect where seemingly all commentators and journalist are under Oscar's spell (or paycheck).
