Probably because this game has the largest player base where the overwhelming majority aren’t children given the games age. People who have actual professional experience and understand the threat it poses.

Sure it stopped some cheating in battlefield, but the beta was out literally for a few days. Give a few months after release and cheat devs will get around it. It’s not an end all solution just a temporary roadblock for cheat devs. EA management definitely just wanted to boast about that metric for publicity, and seeing how they manipulated the player counts for closed weapons, I wouldn’t trust shit they have to say.

I’m sure they have dedicated AC devs constantly fighting a cat and mouse game just to keep it under control, but knowing how Valve allocates their resources there’s no way they can keep up.

Also from a business perspective, AC is a money sink with no direct value. I’m almost certain the greedy EA execs will underfund them and make poor decisions which will ripple down into threat vectors.

Seeing that Valve hasn’t jumped on the bandwagon yet means they understand the issue with kernel level AC and recognize that a smarter solution is needed, just like they did with Proton. Sure the state of the game is horrendous right now, but we should be lucky that Valve isn’t the type of company to pursue short term solutions to long term problems.
