I'll drop the hot take at the start but third party tools are a failing in a multi-platform game and lack of any proper anti-cheat mechanisms on PC lets the entire player base down, especially PlayStation users.
This parts seems to be forgotten or just willingly ignored in the entire third party tools discussion. Square Enix are developing and publishing a multi-platform game that's also cross-platform and they're failing an entire group of them by not properly enforcing the existing terms of service.
Before people do the "console OMEGALUL" thing that I've seen a lot around the plug-in discussion, they're a massive part of the player base and in Japan there simply isn't the PC gaming that's in Western markets. There's a duty on Square Enix to design a game that's fair and equal for the entire player base regardless of how they choose to play. This extends to the toolset available to players via the default UI and ensuring both input methods (controller and KB+M) are both balanced.
I appreciate some of quality of life user interface mods but at the same time, some of these are a product of people playing other MMOs and wanting that same experience in FFXIV. A notable example with streamers was Limit Max getting an exact replica of his WoW UI in this game but that also extends to plugins to replicate mouseover macro functionality that WoW has which I personally know many people that use.
Square Enix seemingly don't like to truly confront the player base in a way they'd take negatively and up until now, every discussion on third party tools has mostly been rewording the terms of service and asking people not to use it. Unfortunately the game is too popular for the "don't do it stance" statement to actually work anymore and the solution is proper moderation from SE, not self-moderation from the community.
At least they finally addressed the implications of console support in the most recent letter regarding third party tools but until they're actually willing to implement the client-side anti-cheat they'd need to enforce this, absolutely nothing changes. They're between a rock and a hard place. On one side it's ever improving plugins with more visibility than ever. On the other side it's implementing an anti-cheat for the PC users so they can actually solve the problem.
