what is wrong with you guys

Actually all PC games are NOT filled with cheaters:

-Mobas like HoTS/DOTA2/LOL have virtually no cheaters outside of a few people using scripts to automate certain tasks/attack combos. 

-Overwatch has 'some', but they generally need to keep it more subtle.  They can't just blatantly rage cheat or they'll lose their paid account after enough people report them, and then they'll need to pay money for a new acct.  Also by the design of overwatch it's actually possible to overcome cheaters (Or at least make life hard for them) just by drafting a counter to their particular hero and focusing them. 

-FN also has 'some', but their AC is extremely strong and makes it pretty hard to stay undetected for long lengths of time.  They also manual ban blatant offenders in less than a day usually.  You would never see anything like the lvl 30+ cheaters from Apex over in FN.  If you wanna cheat in FN you basically gotta make a few new accounts every day and get used to playing without skins and such.

In conclusion, Apex has two main issues.  A weak anticheat system and it's a free game.  You can get away with one or the other, but if you have both problems you're gonna have a lot of cheating in the game.
