Can Newey get his 4 WDC titles back now?
Remember that two of Vettel's WDC's were mostly a gift from tire competition --- and an overly-thin lightweight tire designed specifically for his car. (Remember all the trouble the other teams had with that tire? Remember a six car USGP?)
The six car USGP (Michelin teams DNS) was 2005. Vettel's first GP start was USGP 2007 replacing Kubica.
