I was trying to create a scenario where a) a driver - in this case, Verstappen - who was unable to win the WDC was impeding Hamilton, but b) actually had a reason to be doing it, such as helping his team win the WCC.
So let's simplify it: Hamilton has a twelve-point lead over Rosberg. Rosberg leads, and Hamilton is second. Rosberg starts backing Hamilton up, hoping that Vettel and Verstappen can pass him, and he wins the championship. In other words, exactly what happened last night, but the other way around. I guarantee you that the people who defend Hamilton today wiould be the same people who are first in line to condemn Rosberg.
The point that I am trying to make is that there is a double standard among fans: Hamilton is well within his rights to do X, but if someone does X to him, they'd better watch out. Earlier in the year, Hamilton was apparently free to ignore team orders if they were inconvenient, but expect Rosberg to obey them if asked.
