The communication between the parties is not clear and the competition is back and forth between the parties, and unfortunately it has a negative impact on the crypto market. I don't support anyone in this situation, but looking at the long-term I think this also needs to appear for the market to be stronger after various crashes. Both the SEC and CZ have their own arguments, from an investor perspective with crypto I can also feel people are afraid that binance might collapse after this event, but for me the optimism with the market This school is more, facing many serious situations in the past, I feel that everything will be better.
Yes you're on point the SEC is the government in disguise trying to control and ruin the crypto ecosystem, many people might think they're doing their job, maybe cause they didn't invest with the said exchanges attacked, but the question is after coinbase or binance, who's next? This question would hit hard when the exchanges they're trading with are being attacked by the SEC as well.
They literally can't have a target bigger than Binance, it is the top cryptocurrency exchange out there and they know how widely it is being used by cryptocurrency traders over the world, and they also understand how much of an impact this case will have on the overall cryptocurrency market since there will a lot of FUD, panic selling, and fear among institutional and retail investors which cause the market to plunge.
Authorities can't see cryptocurrencies take over the traditional financial systems so they can't just let it happen and will try their best to cover up and keep them away from the citizens as much as they can, but eventually, we will see them failing in the long run.
