Apparently Hamilton asked Mercedes to drop the protests on the results. If true then that just shows Mercedes are bad losers.
As far as the FIA being inconsistent, yeah they have been. I've seen a lot of people on the internet saying the FIA are racist because they don't want a black person to have the most championship wins. No.
If that were true, Hamilton wouldn't have the most wins and wouldn't be tied in first place with Schumacher for championship wins. Also during Silverstone this year, they would have DQ'd him after the incident he had with Max. This would have put Max in the lead during the final race by a fairly decent margin rather than it being tied. In fact, he wouldn't be racing at all if they were racist. They'd come up with some stupid rule as to why he can't race and his seat would be taken by some one else.
Not only that, but Hamilton isn't going anywhere next season. There are big rule changes for next season, but I doubt Mercedes are just going to drop off in performance as a result. I'm pretty sure they'd still have one of the quickest car on the grid so there's a good chance Hamilton could still get that 8th championship.
What's even more ridiculous are people saying Max doesn't deserve the win. I am pretty sure the Red Bull is a better car, or at least it was during the first half of the season. You can tell just by how many laps Max had led during the entire season.
Mercedes won a lot of races through having a better strategy than RB. Both drivers deserved to win the championship, they're both extremely good as are the teams.
