At this point it’s hard to tell if people are actually genuinely annoyed at MM or more so Lewis didn’t win the WDC.
We’ve seen the lack of inconsistency from FIA favour so many different drivers in the past, including LH, but the amount of uproar here this time I don’t think I recall ever seeing before.
Because this wasn't just a 'lack of consistency' from the FIA, this was choosing to rewrite/reinterpret/throw away the rules on the fly and create an unfair playing field.
At the point the safety car is called, Mercedes are presented with a choice (historically always a bit of a crap choice but that's how it is). They can stay out for track position or pit for better tyres but sacrifice the lead. They'll have mounds of strategy data telling them the likelihood of needing to go racing again at that point in the race and on that basis, they make a decision based on the expected rules - there would either be back markers between Lewis and Max if it does restart that quickly or it'll take long enough to sort them out (as per the written rules) to see out the race distance so the best (arguably only) choice for them is to stay out. If this happened 5 laps earlier, i'm sure they'd have pitted, sacrificed the lead but been comfortable they'd have had a few laps to run at Max with a clear pace advantage.
What Masi did was change the parameters completely to force a restart sooner than expected and without following the established procedure either way, which the FIA have justified with 'well we're interpreting this other rule to mean the director can do whatever he wants' - you might as well throw the safety car section of the regs away at that point. This means that the decision Mercedes made is no longer based in the reality they're then presented with, a reality that more than likely would have seen them pit, if they'd known that regardless of anything else, Masi was going to force at least one racing lap with no back markers present. This isn't sporting and it certainly isn't fair behaviour.
This all becomes doubly bitter when it all happens moments after Horner says "we need one lap" to Masi over the radio.
