Agreed. Definitely not trying to say encryption is a poor strategy. But it does seem obfuscation is most of their anti-cheat techniques.

But the larger point I was trying to make is that all these studios are very secret about anti-cheat but they all seem to be fighting the same battle. Makes me wonder if the industry would be better off with cross-studio collaboration and open-sourcing anti-cheat libraries (that won't be defeated by knowing the details).
