I don't doubt that you may be true, but HN was full of comments explaining how FTX/Alameda is not a scam, but how they use deep knowledge, domain information, how they are ruthless and efficient, how they are scientific and disciplined, how they are "real sharks", etc.
Alameda was legit making money; their strategy was to be long everything with leverage - all the time. Mathematical geniuses in a raising market, lost 100bn in a declining market.
