There is no one behind the scenes trying to make Lemmy more addictive like seen at other major social media giants where employees openly talk about being like drug dealers.
Lemmy is also not using algorithms to push political content or advertising. While these both exist on Lemmy, no one is being paid to push these into your feed.

Anything can be addictive, but the defining feature is causing problems in your daily activities of life. I have yet to hear about Lemmy causing this issue but I have seen this on other platforms such as FB, Snap, Insta, X, etc.
