Too many people are confusing the two. Whenever lemmy.ml or its devs do something stupid, people go “Lemmy is getting worse and worse,” or “I’m leaving Lemmy,” or worse, “I’m leaving for Beehaw.”
If you’re using Beehaw, then you’re using Lemmy. Lemmy is the software these instances run on. If you don’t like lemmy.ml, join another instances that have rules that match your philosophy. Some instance hosts authoritarian or fascist shit? Turn to another Lemmy instance. Lemmy.ml is not even the biggest instance. People who just joined and are unfamiliar with the platform will just think the entire Lemmyverse is run by autocratic admins if we don’t get our terminology right.
I think there’s a difference between upvotes and karma. Seeing upvotes on a particular post is nice. Having a score of the sum of all your upvotes and having it displayed to everyone is a different matter, in my opinion. I feel like it gets taken as a gauge of the quantity/value of a person’s contributions, when there are low-effort ways of gaining karma, hence the problem some may have.
Its a gamification tactic to keep people addicted to Reddit. It’s definitively not a good thing, in my opinion
