He isn't going to "take power" again. He was barred from serving as a Binance executive as part of his plea deal.
Yes. The terms say he would never be CEO of Binance again anytime in the future but will remain part of their board /executives given the fact that he's the founder. He might not be the CEO anymore but I think he will have huge says on the decision making processes now that he is back.
I know that cz has a lot of supporters that will make a lot out of his release from prison, but in my honest opinion, it is not really a big deal, he has served his time and it is up to him to decide the direction he wants to take from now moving forward. When you say he will take 'power' again, you have to be clear with what you mean, i personally do not think he will be actively involved in the crypto industry, and i guess it is for the better.
He did say he would still in crypto just not as the CEO of Binance. I think he would become more of an angel investor since he said in one of his posts before going to prison that he would be more actively investing in projects in the space.
