You should cite these "scary things". If there was a security issue with EAC, it would be significant news and worth discussing. After all, the central premise is that these drivers are secure. The entire reputation of kernel-based anti-cheat rests upon the software being secure and detecting cheaters.
It has never been a problem before. Why would it be a problem now? This isn't some random company. This isn't Capcom with their shitty Street Fighter anti-cheat that didn't hold up to 5 seconds of scrutiny because it had a super obvious backdoor problem. This is from Denuvo, who are responsible for one of the most successful anti-tamper solutions on the market. Their technical skills and quality of work are adequately demonstrated.
Someone has to be the first game to use the new anti-cheat.
If a security issue manifests I will gladly eat crow. If I'm wrong, I'm wrong. But I don't see why it would happen. The idea that one of the most security-oriented and scrutinized drivers in the system will be a security hole is highly, highly implausible. Nothing is impossible, but this whole thing reeks of paranoia and fearmongering. Well intentioned, sometimes, I think. But this feels like anti-Denuvo rhetoric under a different umbrella. People latched onto flawed arguments around Vanguard and are now repeating them verbatim for this anti-cheat. All these buzzwords about "kernel anti-cheat" and "ring 0" as being some scary thing you should be worried about appeared very recently.
There were people who spread claims about the Epic Games Launcher spying on your because IT READS YOUR CERTIFICATES. And it's like, "Yes... That's how Windows works. You need the certificates to connect to the internet over HTTPS." Totally normal behavior shared by all contemporaries gets spun as nefarious and scary.
Complete nonsense got thousands of upvotes on Reddit because people wanted to believe that EGS was evil Chinese spyware. Now people farm karma on Reddit by weaving horror stories about benign anti-cheat systems with no known security vulnerabilities and rigorous safety precautions. (It's kind of amazing how many people glossed over that Vanguard was incapable of bricking your PC by disabling mouse/keyboard drivers, for instance, since a simple reboot would make them work again.)
