Almost 90% of lemmy is ex-redittors.

I have become very tiresome with how those mods seems to be on some sort of power trip

In my experience, that's only on lemmy.ml and maybe one or two other instances. If you go there, just know the entire vibe there is (seemingly) "westerners bad, liberals bad, all hail communism cause capitalism is a western liberal ideal!" or some other variation of that whole backwards ideology.

There's a couple instances that have their heads so far up their own asses that they've become their own Adam's Apple, and those ones are usually just mods going on power trips because someone called them a bad name.

Ultimately this place is hardly different than reddit, aside from not being a corporate megastructure that will sell your post history to the highest bidder (but that might change, so stay vigilant). You'll learn what instances/subcommunities are worth seeing--and which ones are best avoided--in time.
