What if Schumacher had fought and had taken Vettel out and been the deciding factor?
I don't think the FIA need to get involved in penalizing drivers for yielding. Where would the line be? Massa letting Alonso past is OK, a Torro Roso letting a Red Bull past is wrong, a HRT letting a title Challenger past is OK but a midfielder letting them past is wrong? It would be an unmanageable mess.
I understand the what you are getting at, but lets spin it back again. Had Petrov moved out the way and said he didn't want to be involved in an incident with a title contender and Alonso took the title, what back in 2010 would your honest reaction have been?
You could end up in 97 scenario again with all sorts of shady deals being done. I remember the initial anger at Glock when they though he slowed to give hamilton the title, unfortunately I was one of them
