He didn't though, this is just flat out wrong and shifting the blame.
He didn't lose anything going in to the final race. Hamilton went into the final race level on points due to consistently terrible decisions by his team, terrific team strategy by Red bull, amazing driving by Verstappen, nothing more, nothing less.
The reason he lost the title is because of the feck up by the race director. He did everything in that race to win the title, Verstappen started the race in p1 on faster tyres and wasn't able to do anything with that, Hamilton built a gigantic lead that only got eroded thanks to Perez parking the bus through fantastic driving, he then built up a huge lead again and only lost because of the race director. That's literally the only reason he lost the title. Everything else you mentioned has nothing to do with him losing the title, and only has anything to do with setting us up with an exciting potential finish going into the last race on level points. Verstappen did literally nothing in that last race to deserve the win and was outclassed by Lewis the entire race.
The only reason he won that race is because Perez did absolute work for him, and then when he lost that lead again his team made the strategy call to pit under the SC which if the race director adhered to the rules, would have lost them the race and been looked back on as a poor tactical decision by Red Bull but because the director fecked up, ended up working out beautifully for them.
