So I have been using tumblr forever (well -- for quite a while) but I really haven't paid attention to what is going on behind the scenes.
I was quite active around opposing the porn ban and the nudity ban and so on (not because I am a fan of porn or nudity -- I mean I am, but mostly because I am more of a fan of free speech on tumblr, but that's not my point) but as for the backend stuff (not a metaphor in this case!) like yahoo and the fediverse and wattpad and so on........... I have no idea what any of this would mean.
So if some nice person could give me a summary I would be very grateful, because it does seem to be a topic that ignites some passion and if tumblr is about to crash and burn I'd like to get some advanced warning.
