The thing about the work mods do is that it's mostly invisible. If mods are doing their job, spam is getting deleted, reports are being serviced, and no one notices a thing. The subreddit seems to be working fine without them! It'd be easy to trick yourself into thinking they provide no utility. Even worse, since you don't notice the good work being done, all you do notice is the bad work (i.e. power tripping). Which, don't get me wrong, can be bad.
But tbh the complaints I've heard about "Orwellian" mods are completely overblown. I've used reddit for over 10 years and subscribed to hundreds of subs. I've had my posts removed by power tripping mods maybe a handful of times. The number of times I've seen a subreddit go to shit due to lax or nonexistent moderation is much much higher.
