I don,t like any of the teams cheating and you don't care.
I do care.
If a team breaks the rules, they should be disqualified, nobody is questioning that.
If a new rule is created, it is applied from that point onwards, and should not be retrospectively applied to previous results. Thats my point.
So for the specific example that sparked this, if RBR run an engine map, and after the race the stewards check it and find that it breaks the rules then they will be disqualified. However, if after the race the stewards look at the maps and find that actually they want to stop them, and so write a new technical directive/rule/clarification that bans them, they are illegal from that point onwards, and the result stands.
Clear?
