I think it's not that easy to answer because there are, of course, already plenty of cheaters around. On PC most likely with ESP and aimbot (good cheaters hide their hacks and try to play normal), for console I got laser beamed by several cronus guys in the row with insane round stats.
The second point, as already mentioned is the very very bad net code, server side lag, which makes you feel that people are cheating because of the delay / desync which you will then experience as wall / corner and even one shots most of the time.
I played BF6 fair enough, 300h in right now, cheating, generally speaking, definitly increased since Redsec launch and the last two weeks. At this point, it seems like Javelin Anti-Cheat not working at all. I get cheaters every 2nd round.
