if you don’t know what happened: people who were annoying enough to be banned from 4chan destroyed the site for good and leaked hundred of emails and data of moderators and owners and also the entire source code and the owners literally pulled the plug because it was unrecoverable
a lot of people are saying this will be like the Tumblr exodus all over again but, I don’t think that it will happen or be on the same scale as the Tumblr exodus for 1 reason:
the Tumblr exodus happened because Tumblr took away what majority of Tumblr users were there for (porn) while Reddit and Twitter allowed it, I don’t think that Twitter or Reddit will allow what 4Channers will be looking for in 4chan replacement ie. an ability to say or post practically anything they want.
They’ll just go to a different imageboard. The only reason why there was an exodus of Redditors to Lemmy was because the interface was similar. Same with Twitter to Mastodon and Bluesky.
