@PraetorOfOlea EA absolutely cares about cheaters and the game is certainly less profitable if cheaters are not taken care of. And as David has said, EA takes cheaters very seriously and they keep on banning thousands of them which I truly appreciate as I've yet to see a single cheater in season 9 (unlike season 8 where it was an absolute hack-fest).
Please don't spread the idea around that "EA doesn't care about cheaters". It's a very difficult never-ending battle and in fact Apex Legends is actually doing well IMO as I came from CSGO which is a very old game with a promised grand plan against hackers that ultimately failed and is what's dooming the game right now.
OP's idea to add a kill-cam in Arenas is good, however. I think every player should see their kill-cam at the end of the round. This would make every report in the Arenas more significant as players would be less likely to throw reports just from the slightest of suspicions.
