To be entirely blunt. They will never crack down on third party programs like Cactbot, plugins, mods and so forth more than they already do because it's simply not financially beneficial. Square Enix only stands to lose subs if they were to suddenly break every single add on from ACT to texture mods. On the flipside, they won't gain any by removing them. Basically, there is zero incentive for them, especially when they can take their current approach and reap all the benefits without dealing with any consequences.
