I think Square Enix should look into possibly using Easy Anti Cheat for XIV

[linay]

there are things they could do to break addons, but it would break all of them, not just the "black" ones.

If their official stance is they don't want the use of addons, then might as well break them all or it might come off as being hypocritical. At the very least, they could try to break all addons that try to manipulate game data. It would be better than an anti-cheat software.
