> Lewis Hamilton made his first huge win by ignoring such an instruction.

Excuse me, what exactly are you referring to? His first GP win was just a regular race without any controversy, and his first championship win was... not impressive, to say it mildly. He did everything to lose and was only saved by Timo Glock slipping on the last lap.

It is also known that Hamilton was always favoured by the team owners and often benefitted from team orders throughout his career.
