Reddit will get increasingly worse the moment they go public, even if they backpeddal on all of the BS (and they did to some extent), I'm already envisioning several Twitter/Twitch/YouTube-like anti-user monetization features that will trickle down one by one over the years. The owners and admins have shown their true colors, there is no undoing that.
If it weren't for how rough (and personally, confusing) Lemmy is right now, I wouldn't even consider going back. But if the growth stalls, and communities remain super small, I might hop back, which is why I haven't deleted my content and account over there yet.
