Doesn't matter if someone wins a championship on double points or not. They're still WC and that's all that matters. The game is about winning within the framework of rules and regulations which are the same for all.
Also I think people are reading way too much into the phrasing of someone who is speaking in what isn't his native language.
The viewing figures for races after the WC is sewn up are dire so I don't blame them for trying something. The mistake they made was bringing it in in a year that had massive changes already. If the double point rules was in last year I bet we wouldn't have heard as many complaints.
