Security is a big thing, along with performance issues. The consoles are so much lower performance wise than a pc can handle, and they can't guarantee or moderate all mods that people could create, so it could easily crash and over run consoles!am honestly not sure why consoles can't get mods, I never thought about the privacy thing I i just assumed maybe they weren't strong enough to run them, half the time updates from the game Devs themselves can lag an crash games
