People saying they had to defederate to protect their privacy were always fucking dumb in thinking that affected anything anyway. There is practically no downside to federating that doesn’t already exist eitherway. Although it matters more for mastodon than lemmy but the benefits of federating (more users, more content, more friends etc.) outweigh the negatives in my opinion.
In my opinion they do not. When considering the meta userbase we really should spend more time thinking about the quality of those potential new additions than the sheer quantity. Right now, many things that make typical social media so annoying and uninteresting to me are not notably present on the fediverse.
No overt narcissism, less tiktok content, less utterly mediocre people talking into their camera about the most average and uninteresting things imaginable. In comparison the culture here is friendly and nerdy. I don’t think it will be improved by a massive influx of shallow, vapid crap.
