Just a shot in the dark here, but do you have ambient mode enabled? (that annoying glow light around the video). I’ve read from various people that it can use an insane amount of cpu on some devices. Disabling it fixed the performance issues they faced.

I don’t know about it. Look even at the usernames. It’s @name@instance.addr, it’s structured like an email. Even for instances, /c/piracy is not a thing, it is !piracy@lemmy.ml in Lemmy world. Even Mastadon has the same structure of name@instance.

Every community has their own sets of rules, own set of moderators and culture. If you don’t like how one is moderated, go to another one (basically how reddit works too, except there you need to change to name to make an alternate community)
