You seem to be buying into dumb ideas.
It was not up to CZ/Binance about whether FTX got regulated or not. The claims that CZ/Binance was controlling FTX because CZ/Binance had a 20% ownership in FTX is looney. FTX paid that loan back to CZ/Binance, in part with their crappy FTT tokens.. and also FTX had gotten themselves into shitty circumstances because their growth was based on marketing and hype, while the same time they were gambling with client money in a variety of ways, and they were setting up scammy and dishonest systems to convolute their scams right from the start.
FTX survived based on Gambling, and they were running a ponzie scheme.. with SBF acting like a socially awkward honest person when he was scamming and calculating the whole time to sell his image in order that more and more people would throw money at FTX.
Yeah of course, CZ and Binance are favorite punching bags, and sure the FTX trustees can try to claw back that money from Binance/CZ, but they still need a legal basis beyond the argument that CZ is a BIG Meanie.
