I woulda thought if anyone would be protesting it’d be Alpine. Those guys really had a rough run.
Nothing for them to gain from it. They smashed their cars out, regardless of how the order was decided, they wouldn't have gained anything.
On the subject of the complaints about them red flagging and wanting to conclude the race by racing, I seem to recall there being a lot of backlash in Italy last year when the race finished under safety car conditions, now I know some of the annoyance came from how long it took them to deploy it, but also from the fact we were denied a racing finish. Lots of fans, the drivers and team principals all said it shouldn't happen and races should finish under greens whenever possible. The FIA/F1 have delivered that today, and people are complaining anyway.
The grid start under red flags rule came in to effect because people complained about anti-climactic race resumptions from red flag periods, now they're complaining about grid starts.
The FIA and F1 are between a rock and a hard place, because whatever they do, people will complain and whine about it. There was backlash for the opposite of today happening in Italy, backlash today, backlash in Abu Dhabi, backlash in Monaco a few years ago for the rolling start. And as I say, it's not just the fans, the team's and drivers have all said races should finish under greens not yellows, they've red flagged the race, which a) was the correct decision anyway, and b) ensures resumption of racing to the finish. What they can't do is predict a crash, they can't predict poor driving standards, or car failures. The only thing they can do differently to appease as many people as possible is resume via rolling starts again, but what would have happened today? Everyone would be complaint the Verstappen won by 10 seconds and it would have been more exciting if it was a grid start...
