Most cheating in ED comes from players with relatively new or free accounts. Odyssey won't be free, and Frontier has generally been pretty good about taking action against people found using process manipulation, but if an ESP or cheat in which simply reading memory becomes useful, it could become a problem. Some cheats don't modify the game in any way. Instead, they provide a user with information that gives them an advantage, one which can't be 'proven' with a video recording. The only solutions for this kind of problem are A: rapidly stay on top of memory access anti-cheats by reverse engineering distributed cheats or B: modify the gameplay so that such cheats aren't useful. A requires a significant cost, and B often requires a major sacrifice in game quality.
Although, given what Frontier has done to their image with things like Dav's Hope, Jameson Crash, shield booster engineering, or instancing/blocking to name a few, whatever quality this game loses from a few Odyssey wallhacker aimbots will probably be dwarfed by lingering conceptual design mistakes.
