Sadly, Reddit has likely won the short-term battle. But hopefully, this Blackout raises awareness of the need for alternatives. Whether it be Lemmy/Kbin, some up-and-coming site like Squabbles or Tildes, or something not yet created, the seeds of migration off Reddit have been planted. If Reddit has such apathy for its communities pre-IPO, just imagine how bad it will be post-IPO when they are dealing with Wallstreet directly.
Maybe it's nothing, but Reddit seems particularly sensitive towards kbin.
