yeah didn't they precipitate the crash by posting that they were doing thing similar to Luna, and then once the thing is crashing they say they'll buy it, and now they might not even buy it, I'm sure there's a lot of shit going on lol
More than that. Their first move was cutting trading fees, which made FTT worthless (it was useful before for traders to use to reduce their trading fees but with free trading on Binance that became worthless). After Binance made FTT worthless, they then started to sell theirs off (knowing that it's worthless because it's a race to low/free fees). A bank run would have been inevitable anyway as large traders would rationally sell their FTT and move over to Binance for free trading (they pay zero fees and can pocket the money they can get from their FTT). CZ's tweet just accelerated things.
