The two cases are different but they've seen what happens if you're not 100% honest. FTX was big so it did fraud playing dangerous gambling with investors cash. Binance didn't defraud investors or steal but it tried to dominate the American market as fast as it could've so cut corners which's why they faced laundering allegations.
Well we knew SBF was a criminal as soon as his claimed bankruptcy last November. But nobody would of expected CZ to actually be charged with all this.
His exchange was actually fairly honest and never scammed or defrauded individuals. This is why it was a shock to many and many are saying is was blackrock that claimed this needs to happen for the bitcoin etf to get approved. Binance just was way too big and they want the market share to separate.
