Sadly, denigrating other people work is a good way to look smart without having to create anything ourselves. That's why I always measure a new software through the question "what new thing it allows me to do or what does it make simpler?" rather than "what are other people thinking about it?". In the case of the fediverse, the value proposition is quite clear : it allows to have a social life online without being at the mercy of BigTech, through interoperable softwares. And in the case of Lemmy, it allows to do that to replace Reddit. So yeah, some people don't like it, whatever. :)
