Bottas was no guinea pig. 11 wins is more than any #2 driver was getting. Over the years Bottas had virtually equal treatment. There was only a race or 2 he was asked to give Lewis the priority, and that happened when he could not go faster. For what Hamilton has accomplished, he hasn't received true #1 status even with all those championships.
It's unfair, but he can only suck it up. He has no one to seek justice from. All he can do is drive the nuts off the car harder than George can and try to qualify better. Bono is probably upset Lewis is leaving him also, and will give Lewis the short end of the stick without hesitating.
Interesting situation at Merc, but it makes the season exciting to see how Hamilton deals with the adversity. Can he come out on top while getting the Mark Webber treatment?
