Reddit's long-term downhill has long-started, API changes was part of the beginning and now, it continues. If Reddit goes public, the need to please investors, VCs and so on will make it even less ignorant to what the users wants.
It has never been a better time to switch to Kbin or the fediverse in general.
Techies will care, most people won't. Niche communities will still be on Reddit. It's just easier and data never gets lost (as has proven to be the case many times in the fediverse).
Not lost entirely, but there have been tons of times lately where the answers I look to reddit for are deleted or the discourse in the comments is peppered with deletions to the point that the narrative is gone.
You're 100% correct, but I think this issue has a time limit. Fediverse already can pretty much do everything reddit and twitter does, but still has loads of potential to innovate in areas that those services won't/can't.
