How is it a bit like AD 21? Two completely different situations. One is another team cheating which ultimately didn't affect the title result because there is no rule to allow a whole race to be annulled (nor should there be), the correct action (disqualification) would put Hamilton even further ahead. The other was actual multiple rule breaks by the race director to set up a scripted finish which definitely changed the championship result.
Imagine if Massa wins, enjoys his title for a few years, then when Hamilton retires he takes legal action over Spa 2008 and AD 2021 to get them back.
