From a technical standpoint, there’s no functional difference: without secure boot and OS attestation, age verification is as ineffective as EAC on Linux, because you can simply `insmod GameGenie.ko code=A456-GH4C` to have your mobile device simulator kernel patch success into any challenge. At the surface level they’re different — one is PvP, the other is PvG, one uses webcams for Twitch, the other uses webcams for facial recognition — but the same set of kernel defenses enable both.
