Sorry but the 'twitter will die any day now' narrative was utterly pervasive across reddit and endless media sources were cited on a daily basis in the 6-month period that followed the buyout. It was basically the _only_ topic on r/whitepeopletwitter which had 3+ posts hit the frontpage daily.
It isn't something you can gaslight away. Everyone who was there saw it. It happened.
Interestingly enough most of the reddit posts were deleted after 3 days once they'd fallen off the frontpage. It didn't matter, there were always more being made lol. Does make it awfully hard to cite, though. Odd.
