I don't get all the FUD around anti-cheat in a multiplayer game. I've played many games with anti-cheats that work and don't cause any problems. My computer still works, my games work and I don't have any issues with software. I've seen people get bans because they've used the same VPN as a cheater but that was over a decade ago in some obscure FPS game that's dead now. Likewise, Luke from LTT (LinusTechTips) got banned by Blizzard's anti-cheat because he left Visual Studio open when playing (and one part of that IDE includes a memory debugger that reads the memory of running processes which is also something many legitimate cheats do).
WoW's anti-cheat is separate from the add-on framework. Warden is to stop bots such as Honorbuddy (rotation bot was one function of this paid cheat back in WoD/Legion) or Tmorph (allowed you to change the model/armour of your character locally before transmog (glamour) was an official game function in Cataclysm).
Blizzard control addons and have broken things such as AVR and certain WeakAura functionality. More importantly, they can live patch the game client to change some of this behaviour without having to do server maintenance or even pushing a new download via the Battle.net launcher.
There's massive misinformation about addons in WoW and in reality, the extreme end of plugins in XIV is much more egregious than anything you can do in current World of Warcraft.
I'd say Blizzard do a much better job at enforcing their terms of service via more effective punishments. Honorbuddy ban waves in WoD/Legion were a prime example of this. It wasn't an instant permanent suspension for this, it was 6-month (first time) and 18-months (second time) suspensions alongside returning to your characters have no gear, inventory or gold (Gil in XIV).
More importantly, and SE have never seemingly done this, is that the ban wave dropped during peak raiding hours. Honorbuddy ban waves hit during peak hours when more people would be raiding etc and you'd be more likely to notice your guilds top DPS players, for example, suddenly going offline. They knew it would kill guilds etc but did it anyway.
The closest thing XIV has to this is Party Finder being less active when plugins are broken during the first few days post patch. We all know those people that suddenly don't play because their totally legitimate third party tools are broken, maybe you should think twice about them next time.
