Hi, I am PC player who never used cheats or hacks. Sometimes i meet cheaters in rivals and champs but that is not even close to the word "everybody".
When you say "everybody is cheating on pc" and then you say "pls do something" what do you expect? To improve anti-cheat? That won't happen in closest future. To remove PC platform from FC? Same answer.
I kind of understand why people use cheats. Of course there are some kids who just think that it is funny to play with cheats. And there are people who experience unfair gameplay that feels very similar to facing a cheater. But not exactly.
If you think that literally every single opponent is cheating on PC (that is nonsense) then just turn off cross-platform in matchmaking settings.
Good luck.
