Marquez deserved it. It was his own fault/teams fault, not the FIA, that they blatantly ignored what were VERY CLEAR rules. I'd say the same of webber if he did something similar!
Actually Marques did nothing wrong, it was a pit board error.
That said ........
they had only a window of two laps to do that tyre change
it was something new , not normal
They don't have radio contact.
Several teams made the same error- shows there was confusion.
I still say the punishment was too draconian for the crime. No intent to do wrong, a small error, on which the title could rest.
