Indeed a very good Fediverse article from David Pierce in The Verge. 1 quote

'But if our current social system was decentralized, you’d be able to post a picture on Instagram and I could see it + comment on it in the Twitter app. Your friends could read your tweets in their TikTok app. ... Different apps would have different strengths and weaknesses, ..., but you’d have the same set of followers and follow the same accounts no matter which platform you use.'
