Yes FTX done a mistake but CZ wanted to shutdown FTX to kill competition. FTX was growing alot quicker than other platforms and Binance felt like it was a threat for them. CZ has the Chinese intelligence agency behind him he is backed by the Chinese state, if people didn’t find out yet soon they will when the staged “Binance biggest hack” happens and users funds head to addresses controlled by unknown group (Chinese controlled addresses). The chickens will come home to roost.
In business, it is not uncommon for competitors to destroy each other, if FTX does not make mistakes then binance will not have a chance. The mistake is still caused by FTX being too greedy and unethical in business when using users' money for the wrong purpose. Binance ruined FTX the same way FTX did with Luna and the projects they invested in.
CZ is of Chinese descent but he has Canadian citizenship. If all this is due to the Chinese government pulling the strings then the US government will soon respond with binance, because SBF is American and his mother is a member of the democrat party.
