That's the majority opinion on this subreddit from the comments and posts I've read.

"Greatest night in formula 1 history. Unfortunately it would be marred by r/mercedesamgf1 legal threats against F1, twitter fans, and later even ruining Masi’s stellar career. Rather than celebrating their hard earned second place, they would prefer to ruin the sport."

"Still believe they brought the sport into disrepute with their nonsense. Dragged the process out for way too long. Once the stewards said it's done, it's done. Any entity beyond that is not going to overturn a freaking championship months later. Weaponizing their fanbase against Masi/the FIA, not showing up to the gala, threatening to leave F1/starting rumours about Lewis leaving, just sore losers all around."

"It was all deliberate - Mercedes now can get away with anything, because Twitter said that FIA got it wrong so they won't dare question any complaint."

"He wasn’t .Masi followed the rules.Don’t start your shit again ."

"There was no cheating mate. It was just subjective interpretation of rules. Masi had complete authority to call in the SC and he did. In your books it may be wrong. In mine it is right."

These are just quotes from one thread.
