The SEC was meeting with SBF and failed to protect US citizens who sent money to FTX. So far Binance hasn't pulled a ponzi scam (they existed before Alameda/FTX and have never stolen anyone's money). So basically the SEC failed to protect people from that ponzi scammer boy SBF was, but they're going after the like of Binance and Coinbase, who, so far, never stole a cent from anyone?
The SEC is sending a message that the days of crypto exchanges being largely unregulated are over, and they're probably doing that because of how badly they screwed up with FTX, not in spite of it.
