All of these lawsuits are targeting people selling mods/cheats/whatever that negatively impact the game. It’s mostly impacting people making millions on aim bots, automation tools etc. These tools do also exist for Final Fantasy XIV, Square Enid seemingly doesn’t go after them directly though. Not to mention these other games listed as examples, such as Destiny 2 or World of Warcraft, have client side anti-cheat mechanisms that are also used to prevent unapproved modifications to the game.
