I don’t think anything is un-addictable (making up words here). I do agree that the social media mindset and fedi are not compatible though, basically because of the algorithm concept.
At the end of the day I hate all social media because they feed me what they think I want to eat. Regardless of how well they do that I hate the concept because I want to decide for myself what I want to partake in. Fedi allows that without getting in my way.
