Honestly, the worst thing about Lemmy is Lemmy users thinking it’s better than Reddit simply by the virtue of it not being Reddit.
The platform? Yes, absolutely, a much better solution with built in checks and balances to stop one greedy company eating everyone’s lunch.
The content? It’s identical! (Bar a few cosplay communists that stir up drama occasionally). And some things are significantly worse like the quality of content curation and moderation.
For every person writing an “ugh you must be a Redditor”/“I thought I left this behind on Reddit” type comment,I bet there are many more people rolling their eyes and at least a few of them that end up abandoning the platform entirely.
